Hey!
First of all, congrats for finishing the game! It was really fun to play the game because I like the concept of it. The music fits very well the pixel art style which is great.
If you want some feedback, here's mine: I think the game gets hard really fast, I think that the fact that those spikes kill the player from one hit is a little bit weird, because I have to remember the whole layout of the game. Yes it was fun, but also a little bit frustrating. But other than that, it's a real cool game.
Nonetheless, I think you and your team did an amazing job! Congrats!
I would love to have you playing mine too, if you don't mind of course! ^_^
