The amount of polish is staggering, and the music connects so well with art that it's unbelievable for a jam entry!
Special grats to the guy who did the UI
Things that need improvement are the AI and programming (e.g., around wave 10 of endless mode, the enemies are off-screen, I think, and unkillable, but they die after some time? IDK what happened)
I felt the waves to be far too short and didn't feel challenged; only the boss provided the actual fun of the very nice gameplay.
Ponder on these and then, if u want, I can see it on steam for sure!
