Hey, this is a pretty fun game! Great job, especially for your first game attempt!
I like your art and enjoyed playing while I could, it kept forcibly reloading due to memory usage. I also would have liked a bit more of a tutorial on the first room, maybe starting with movement keys, then jump, then double jump, and an explanation of why my eyes turned red.
I think you have a solid start to a potentially very fun game, keep up the great work! Your mechanics all felt very smooth when playing.
