First of all, thank you very much for your extensive testing and feedback. I'm glad you like my little game.
Regarding your issues:
- I have no idea what the effect of a quick boot is, but I guess the Rust agb framework is not working without fully booting.
- Sound are defenitly very quiet, I put it on todo list for post jam work.
- I had a out of vram crash only once and I tested a lot and wasn't able to reproduce it anymore. It is definitly not easy to leak memory using Rust, as the lanquage is designed that way, but not impossible, so I suspect the agb framework has eventually a problem freeing tiles correctly. But I might be wrong. It is my first gba game and the first time I used the agb framework. I will investigate it post jam.
As I did only test in mgba emulator, was the text in the "How to play" menu hard to read or to small?
Your idea to create different difficulties by making towers not cross the whole board is great, I will think about it and put in on todo list.
Have a nice day and thanks again for your nice comment.
