Wow, it's been a long time since I did anything related to this project. Don't expect anything! It was only a proof of concept to see how fast I could get a port up and running in Godot. It is a LOT easier to work on in Godot, especially since I don't have to rely on my own (bad) physics simulation.
Most of the work done here was getting the code for a spherize shader working, and rendering a texture offset with proper wrapping. This was not feasible when I last worked on this project about 5 years ago.
I don't think this game would ever stand a chance of making a dime these days, so it is unlikely to be completed. Sorry (・ω・`)
