Real cool game, at first I didn't know I could dash up, so I failed and got the bad ending. After that I learned and I could get the good ending, mechanic is pretty solid, I would suggest an update in the dash. Currently if I use dash in the ground near a cliff, the mouse go straight through the hole, which is the expected behaviour of a dash, the problem is when I use dash in mid air, the mouse will fall, which is not so interesting in a dash mechanic. Of course, you can make that decision as game designer, it depends on your intentions. But as a player, I prefer a dash that drives me straight in the air or ground. Other than that, congrats for your game, it's really well developed.
