Why is interlaced mode not recommended on the 500/600? I assume you mean on 512K ChipRAM Amigas?
What language/tools do you use to develop and port the game?
No, CPU power was the problem. I noticed some slow-downs on A500/A600.
The game was written in 68000 assembly. The levels were designed in CharPad C64 Pro, then fed to a Python script.
