I tried both WHDload and HDD version and the game crashes at level 5. I use WinUAE. At startup I have 1936928 bytes of Chip RAM and 128MB Fast RAM free.
Try the version below, it's running on a newer version of the engine that enables more entities on a level (that level is too crowded and breaches the older engine's limits). But it also has new issues on other areas. I'm working on it. Thanks!
