According to how Itco works, if we purchase the Supporter's build for 15 dollars, that should also grant us access to the full game once you release it, unless you up the price more at least.
10 to 15 USD seems reasonable. I mean, the demo alone would be a satisfying $1.99 mobile purchase price, haha, it's that fun.
Looking forward to it if you decide to release a supporter's build. I'm sure if you do release it you'll get a lot of feedback to finetune the final product.
