I'm glad I didn't buy it with money. The mechanics is so bad, the jump and the grab control design doesn't make sense. The enemy design is not challenging. I gave up on way to the third boss (?) Where I can't jump to the platform and have to swim 5 mins to the start point (I tried 10 times, that's enough trial for something so boring). The designers don't know what makes a game engaging. Dying from a hard boss is good punishment; can't jump and got punished to swim is not.
