Tried the last posted ECS version on A600 last night, Viper630 (68030 40 MHz).
The good news is, it runs even with only 4 MB fast ram!
When I launch the game I have 2 MB Chip and 2.8 MB Fast free left.
The bad news is, it is kinda sluggish. It's not terrible, but not really playable full screen. I suspect it would be more playable if I reduced the window size.
Also this is without using HSmathlibs. Those might speed up things a bit. But hey it runs on A600! Who'd have thought that!
