Oh wow I love it!
What I especially love are the arts, the evolution of the levels (wasn't expecting that ahah) and the evolution of the critter itself (omg). The gameplay works very well too, I had a lot of fun avoiding ennemis and playing QTEs.
What doesn't work too well: the game was a bit too easy at first (at least for me), and suddenly hard at the city level. I had trouble reading the dialogues, probably involuntary skipped some parts. Finally, it is a bit hard to see the critter on the background sometimes (backgrounds could be a bit less saturated I think but i'm no expert).
