It certainly is an interesting idea, and as a person who has played multiple rage games before, this certainly got me quite enraged HAHAHAHAH
Unfortunately there is no sound effects nor music which really could've helped, and also binding the jump to instead be something like O/P with AWSD or binding the controls to be ARROW KEYS + Z/X would've really helped, especially since it's supposed to be a gameboy game.
All in all, not a bad submission, keep working on it and I feel that you can have a banger!
Also the intro text is super long and not that great for the eyes, so making it skippable may make it better
