Heya! Thanks for playing the game, I appreciate it a lot.
I'm aware that it's hard to exit the game unless doing a hard reset (the old alt + f4), I actually had it on the roadmap alongside save states but had to cut the features out because of time limitations. I'll work towards implementing them once Artfight finishes so I can properly focus on troubleshooting without bothering the site mods (I've asked for a rating check, so I don't want to change anything major for now).
For the full screen problem, I think I can try to enable window mode as a possibility. I'll look into it tomorrow; for now I wanna rest a bit.
Can you please tell me where exactly did you find the mixed up text? I'll try to release a hotfix ASAP for that! Thank you again for the kind comment <3
