I can tell you that the game is not abandoned, however, new releases aren't being yet released on itch because they are purely experimental. If you want to try them they are completely free on the discord. Maybe the bug that you reported about accuracy is fixed already
wish I could, but I can't download games, I can only play on browser itch.io games. i'm sure you'll take it somewhere and fix the subtle bugs and balance. also cheat codes would be nice to test limits and just have fun.
