Omg, thank you! The donation is really much appreciated. I'm glad the game left such an impression!
I'm on the fence about charging for the next one, but the demo will most certainly be free. If I do charge it will probably just be 1-5 dollars, nothing crazy.
I am hard at work on the next one, which is much more ambitious. The demo should be out this summer, hopefully the final game out xmas or early 2026.
