This game and its concept has a lot of potential to be a full flesh game imo, i assume you are aiming for a PSX-retro vibe, i would recomend to use texture and vertex warping and other goodies to achieve that vibe even more.
Thank you for checking the game out! I'll keep that feedback in mind. I haven't really played around with adding effects like that before, so I'm sure I could stand to learn a lot from trying it out!
