heres an idea for when you become a full time developer:
instead of having a gluten free lad, how about someone going on a diet. Make a cutscene where hes transitioning into having a diet and eventually controlling his sweet and fast food tooth. Then zoom into his brain and then it will go into a level select where then you can play the actual game.
Ideas for the main premise for the game: a bullet hell type game, a sidescroller shooter game.
.. idk why I made this.
anyways, other than my terrible ideas, this is an actual good and challenging game! Keep up the good work and remember, never take any hate to heart, if not genuinely criticism.
