Hello everybody, I already have mentioned a few times I would write a review about this game and here it is now I found the time!
Wario Land 4 is one of the first games that came out for the GBA and one of the first Mario-based games for the GBA. It received many positive reviews and I have played this game many times and I'm very positive about it as well. I don't know how I originally got to know this game but since it has been in my mind for a long time I decided to make this review. Let's get this started!
Story: 7
I decided to do the story first as it's useful to know. The story is not very big. Wario reads about a doctor named 'dr. Arewo Stein' who has discovered a pyramid that is said to contain many treasures. Only thinking about money and not about the dangers, Wario races with his car to the Pyramid. When he enters, he sees a black cat who has been following him and it jumps in a hole. Wario does the same and find himself stuck in a deeper part of the pyramid where he has to go through several levels. It's not a great story but it fits as a good Wario story. And it's pretty interesting as there's a story behind the normal story but I won't reveal spoilers!

Gameplay: 10
This is something I normally don't place reviews but I decided to do it for the first time as it's an important part of the game. In Mario games, you usually jump on enemies, destroy them with fireballs or crush them while using a star. Wario games work different. Wario is fatter and strong than Mario so his signature attack is a good ram with his arm muscles. He can jump on most enemies but all enemies aren't effected by that so Wario can use a good ground pound. If Wario jumps from a great height this ground pound can become so powerful that it can smash through several blocks, which is needed to open up some passages. Wario can also dash and break other blocks with this, although this can be done with his ram attack as well. Wario can also crawl, swim without needing to breath and he can pick up enemies and throw them against obstacles to open up new paths.
Wario can also undergo certain effects. If Wario is on fire he runs around like crazy and he can break many blocks. Wario can become flat and go through certain passages. Wario can even become a bat and fly upwards until he touches light or water!
The level idea is simple. You enter a level, you are supposed to find four parts of a crystal that are used to open the boss of a 'passage' and you need to find a 'Keyzer', an ally that will open up the door of the next level. You can also find CD's that you can later listen to in a music room. However, to get out of a level you need to find a Frog Switch but if you press this you have a limited time before you start to lose your score and ultimately, faint! But if you collect enough stuff and coins then you will get a highscore with a bronze, silver or gold crown by your name!
There are also pipes that bring you to puzzle rooms that usually reward you with diamonds and where you have to throw the doctor around like he's an enemy to break bricks and hit switches.
There are 6 different passages and all are themed differently. There are two small ones, one at the beginning and one at the end and four major ones. The major ones have these themes: Toys, Horror, Nature and Technics. The toy world has levels with block doors, dice blocks, living doodles, pencils and domino races. The horror world has ghosts, magic carpets, lava, and abandoned buildings. The nature world doesn't change a lot; Levels with palm trees, flowers and bees, underwater monsters and a monsoon jungle. The mechanic world is maybe the passage with the most various levels: A factory, a dump yard, a freezer and a pinball machine. The levels are very different from each other and have unique enemies and challenges so that's a great part of this game.
All in all, there is too much to tell everything but the gameplay is just very good and very big, even better than the Mario games in my opinion.
Graphics: 10
If you have ever played a Mario game or a Mario-based game you know that the graphics are usually stunning. This game is no exception. The enemies have interesting looks, the game design is good, the backgrounds fit in with the themes. There are levels with a lot of funky colours, levels with caves and cave floors, levels with machines and so on. Wario, his allies and enemies are easy to recognize and it's not hard to tell who is who. Flames are realistic, water has those patterns you usually see, enemies have funny designs. There are many different backgrounds specially made for levels and levels can contain more than 5 backgrounds!
Sound: 10
This game has many interesting soundtracks. There are 18 unique levels with 17 of them having an unique soundtrack. There is also an overworld music, a shop music, two boss musics, a 'hurry up!' music, a credits music, and even more. The soundtracks have many tunes that fit in with the theme. For example, one soundtrack for a level that's very cold contains many ice like tunes. A soundtrack for a level with toy blocks contains cheery tunes. And a level with a lot of trash and garbage contains... a rock music? That's no problem, it still fits the theme.?
Addictiveness: 9
This game is very addicting. I have played it many times, as you can easily pick up with this game and it's easy to play this even when you have just started. As the levels and the bosses can be replayed as much as you want you can just come back for those. Or you can play to discover more secrets, try to get a better highscore or pick up treasures that you forgot. Why I didn't rate it a 10 then? It's just that the game isn't very big in means of levels and bosses. So after a little while you already have seen everything you want to.
Depth: 8
Like I said in the previous section, there aren't many levels and bosses. But the levels and the bosses itself are pretty big in a way. They require difficult tactics, there are level-unique enemies, even the bosses have unique enemies, there are many small and big puzzles, there are also many things like magic carpets, pinballs, lianas! You can tell the creators put a lot of effort in the levels, enemies, challenges, puzzles and bosses.
Difficulty: 7
Maybe one of the parts that's less interesting is the difficulty. There are three modes of difficulty: Normal, hard and S-hard (super-hard). They don't bring a lot however, the only things that differ are shorter time limits and extra enemies. Then again, I have only played the normal mode so I don't know a lot about it but in general, the levels are easy to pick up and even though you can have a tough time with some levels and puzzles you will easily find out the solutions. I didn't have a lot of trouble with this game in general.
This is the end of my review, as you can see, the gameplay part is very large but that's because I found it the most interesting part of the game. If you have questions about things I didn't cover, feel free to ask them as I can tell more in this review but it would get messy. I hope you had fun reading this and until next time, review readers! Have fun with writing reviews yourself!
