The drawing weirdness in the game is 99.999% likely to be a bug in the game.
Quirks on an Amiga that would be comparable to a BSOD (ie really bad system level problems)...
1. A single buggy program can cause the entire GUI to freeze, requiring you to reboot.
2. A type of bug that commonly occurs in programs written in C, can cause random crashes and data loss in other programs that are running at the time (ie the buggy program corrupts the other ones). This can extend to corruption of data on the floppy and hard drives, because the floppy and HD routines in the OS are vulnerable to this too - the code may be in ROM, but the track buffers are in RAM. C is the "official" high level programming language for Amiga development. Oops.
3. You can't move windows so that they're partially offscreen. OS4 finally fixed this, and I am forever grateful to whoever implemented that.
4. The Fast Filesystem isn't - use PFS or SFS instead.
5. Recoverable Alerts aren't - it's a single get out of jail free card. Save any data immediately and reboot.
