As the Author points out, not YET translated, not that big of a deal.
The main problem is that it has some major bugs. Holding space seems to repeat the animation of whatever the character is currently doing, whether jumping which makes a jump rope type animation, standing which makes him move around without animation, or using his wall-kick with e skill which makes him go continuously higher and float around the screen.
The levels need to be re-designed, instructions made during the game about what to do could help.. The difficulty level's pretty high too, dying from one hit from the first enemy you see and getting a game over screen. Needs a serious re-work.
dude this sucks i can't jump over some things and not fun
It takes a little while to load. But once it did I found that the platforming was a bit tricky, if not glitchy, the terrain doesn't make sense and the visuals aren't that great. Has potential but needs some polish.
