Thanks for the feedback!
I'll take a look at the bugs. Bacon was probably me toying with shops and forgetting to add an item or two back, I'll check it out. Regarding the crashes, I'll take a look too but more information would definitely help, the conditions for me to reproduce the issue for example.
The game being in real time can work if it's well designed. I'll take my chances.
Regarding tetris, there'll be more minigames eventually.
I'll add a button to move the window around. Regarding minimization, I wanted to try minimizing it into a small widget in the bottom left corner of the screen, showing only your character portrait and some very minimal interactions. But I haven't had much success with that so far. Worst case scenario I'll just do a regular minimize button.
