A fun little idea, and I absolutely adore the concept art! The 3D assets also seemed pretty good, but I feel like you slightly overdid the post-processing effects.
I think the controls could have been tightened up a little. Using holes to escape was a fun mechanic. Unfortunately, it’s also pretty easy to accidentally enter a hole right now.
Lastly, I really loved the music and the sound design, they fit the vibe of the game very nicely!
