The overall gameplay idea is cool, but it is sort of difficult to get into. Without reading the comments, I would not have been able to get through what most people thought is the second room. Also it is sometimes a bit unclear, why the player changes directions or how far he can jump. Also: when I got to 0 HP nothing happened. Despite the ciritque I admire the vision and think that the Idea has great potential. (But also mechanics like only being able to shoot downwards really feel unintuitive/not natural, at least to me).
I would love to see an updated post-jam version of the game!
