The art-style is really great. Music is apt to the game as well. Gameplay is very simple yet engaging. Game mechanics work very smoothly without any issues, whatsoever.
However, some medals would have been great rather than just the in-game achievements. Also the selection of new skills is a bit random in nature as the player doesn't exactly know what it really is, but I believe this adds as an element of surprise.
In its entirety, a really great game by the team. Keep up the good work guys!
