Thank you so much! I wasn't sure if the concept would work out, so I'm really happy you liked the concept (even though the execution of it was far from perfect).
I completely agree on the sound design. The cubes you collect are supposed to represent glitchy audio in the recording, so I tried to capture that in the sound design. Unfortunately I didn't have much time to put into sound design for this jam, so most of the sounds were just edited versions of pink noise.
And thank you for the feedback on the player experience and difficulty! I wanted to include some more difficult jumps that required turning projectors on/off mid-air, to see how far I could push the core concept, but I think more needs to be done to the game to make those types of jumps feel more fair. I ran out of time to add a jump buffer or coyote time to the 2D platforming, which I think would make that part of the game feel a lot better. If I ever expand on this game, I could add a rewind system, which would remove the frustration of manually resetting the level after a failed jump, while also being very thematically fitting. I could also add a way to slow down time in the 2D world, which would reduce the difficulty of the platforming, while giving the 3D character more time to turn projectors on/off.
Thanks again for playing, and for the great feedback!
