This is a very well made game.
That was wonderful, one of my favorite games ever. One obvious bug is that the rightmost orb during the boss battle always falls WAY through the tiles. There were a few other similar tile glitches throughout the game, but none so noticeable. I'm not complaining, it's just that it probably wouldn't be too hard of a fix, and it would make that important moment in the game more polished.
I'm always having a mini heart attack whenever I jump dangerously on some blocks XD Hahahaha It's quite challenging a bit but It's amazing :D
Challenging but not impossible! I don't usually play platform game, but this!
