But cheating the recommendations is not good, that's disingenious, especially if your Game is in this state. People who are young often do stuff like that, but remember that will always be associated with your Developer Name, you are giving yourself a bad rep with that.
If the issues with the Performance and Bugs have to do with Godot, i'd recommend working out the simplest things first without crashing or bugging out. Don't focus on graphics, just build with greyboxes. The Game is walking and clicking things anyways, so the Interactions and Events should work 100% of the Time. And go on from there. Good luck in your future Games.
