Thanks a lot for the suggestions, I'll look into fixing them soon & I'll reply when it's updated! 😎
So far the next update has added a stamina bar. This slowly ticks down while the GIFotchi is awake, and goes down more whenever you play with them. This fixes getting overworked from having too much fun, instead happening when you have no stamina. It also gives another purpose to sleeping as this is how it's replenished.
Another addition is being able to toggle the window to a borderless transparent window.
Going further into the future, I want to add more long-term progression outside of just levelling up.
