Very good puzzle game
Nice! Loads of levels getting more and more complex, but not that repetitive. The music was ok but ended up being annoying. The fast speed button was MENDATORY, it's good you thought about it, I wouldn't have played the game without it.
The map was a nice plus, but it makes the game crash when you click it while a tutorial is displaying. It's not really a problem thanks to the autosave, but just wanted to report it.
Finally, you could have made 2 others animations for questy facing up and down. Rotating your sprite like that gives the game a hastly finished feeling. (Which is absolutely not the case!)
