Wow, thank you for playing, I am very glad you had as much fun as you did! Your interpretation of the game is very very charitable :D
The sprite not changing is a bug that happend for other people but I couldn't replicate myself so i wasnt able to fix it :(
I thought about adding a restart button, but at that point it was already too late and yeah, with no settings the accessibility issues for people with dyslexia and color blindness are pretty apparent and is definitely something to add in a hypothetical release.
Thank you again for playing!
