Okay first stuff, I love thee opening cutscene, explaining the story through image instead of text is really smart I think. The art here is insanely good! Here are some things though:
At the start I tried to go to thee right side but then realized there is just an invisible wall there. you should replace it with an actual wall.
The collisions of the spikes feels a little bit to big.
Overall really nice game, simple and fun!
