I'll follow up on a few points:
For a "shoddily coded" game there weren't any bugs that hindered the experience. I did bump down the settings to "Medium" I think, but it ran smoothly at 90-120 FPS which is what I consider excellent. It's definitely not very optimized, there are plenty of games with higher graphics that run way better.
As for your art, I don't think you have to abandon your current style to improve it. Study some of the basics and practice drawing from reference. Yeah it's not easy, but you can do it!
Looking forward to the Christmas special!
