Hello, in the GBA version when pressing left or right the indicator whizzes across the screen and since it wraps around, it's not controllable at all, it's more like a random generator. Can you implement some rate limiting or only listening for a key down event and not polling and executing the key press each frame?

You're running it through an emulator or an actual device?

It happens on my Nintendo hardware (GBA SP, GB Micro, DS Lite) as well as FPGA based hardware emulation (Analogue Pocket)

While I'm at it, I also found it amusing that depending on the shield you get, the mouse cursor will become visible in the upper left (I think after a palette cycle?) and stay there for the remainder of the game

Oh I just saw that BadDiode did the port. I can get in contact with him directly via fedi, we follow each other. I'd be happy to help with testing on real hardware. Would you like me to do that?
