I tried to like this game, but it just really doesn't appeal to me.
The controls feel slow, and the jump is absolutely abysmal. Several platforming puzzles lead to frustration just because of how short the Character's jump was.
You're also told early on that you can change suits, but the game does not give any explanation as to why you'd want to do this, and how each suit affects you. From what i experienced, there isn't any discernable difference between the suits anyway, aside from the berserker suit.
The enemies are more of an annoyance than anything else, and it's very difficult to dodge their projectiles as your character is rather large. And even if you do get hit a lot, you can easily craft a cheap healthkit that heals most of your bar. Speaking of the crafting system, you can also make grenades. But i rarely found myself using them, aside from when they were required to bypass obstacles, they can also be used to perform an air dash move, but this needs to be charged up and so is only useful in specific situations.
All in all, I think this game isn't really that good. If you like platformers such as megaman, then i'd recommend buying it during a sale. But other people probably won't enjoy this.
