The game was actually pretty fun, but I did want to point out your broke nearly every single gameboy commandment
- Resolution was higher than 160x144
- Mouse interaction. It's okay to bind a button press to LMB or RMB, but UI navigation and moving a sprite with the mouse is a no-go.
- Smooth rotation wasn't a thing
- There were more than 4 colors on the screen
I didn't really understand the button layout either. For example, the gameboy has dpad, select, start, B and A. You have LMB and R listed on your page, but the house requires a key press of E. What do these relate to on the gameboy?
I'm not saying all this to put you down, but to help you for your next GB Jam release. Even though you broke every rule, it was still enjoyable and you did a good job.
