Hello and thanks for playing our game!
I am very aware of the the issues you mentioned, I really wish I could have done a lot more but let's just say we had some issues while developing so we ended up cutting corners
The tilemap is reused from another game of mine (because game jam) and is the only reused asset, and it is trying to go for that dark theme you mentioned but it is still in its early stages, I also added key rebindings to it just before the jam :)
I just need to change it from a rar folder to a zip folder now that I understand the differences between them
