I understand your frustration. With such a tight deadline, I didn't have time to test the final boss on other emulators or on the real console; I only tested it on Mesen. After launching the game, a few minutes before the jam finish, I went to test it on the real console and had a nasty surprise: a visual effect using OPT wasn't displaying correctly. I was desperate and tried to fix it as quickly as possible, but it was taking too much time, so to calm down, I simply removed the effect and released version 1.1 as soon as possible, and then I was at peace. :') Making a game under a deadline was a very different experience, including the ROM size limit. I'd never been so concerned about ROM space and graphics compression. But I feel good about using the SNES's large RAM for something. Congratulations for your game, I loved it!
I used the SNES's background mode 4 in this game, which supports 8-bit per pixel graphics (256 colors). It seems that this GBA thing doesn't support it. Interesting, I didn't know that existed.
One tip I can give you is to stay at the bottom of the screen, Luigi will always come out from the bottom, you just have to be careful with the others who also come out from there in addition to those already on the screen. Good luck!
