you can actually just press the back button under the patreon button and you'll be able to continue. idk if it's a glitch or not but i thought my game was incomplete as well
That is how the back button is supposed to work. You will see the patreon screen quite a few times during the game(and please support the game it really means a lot), but the back button always takes you back to the game and allows you to keep playing. If it doesn't do that, then there is a problem
