Aw, I tried to play it. However, my sad little potato couldn't run my screen recorder and the game at the same time.
btw I am also a solo dev and it's really commendable that you finished a full project. It's really hard.
Dang! You could try running at a lower resolution to see if it helps. And thank you! Love to hear from other solos, just keep at it! Don't give up. :)
