Work has been a bit slower with the AGA version but it's difficult to keep that intensity going for too long. Also when the game has already been finished it does give less incentive to just do another version of the same game.
No system-friendly version, sorry
I can only write games for what I own and all that stuff doesn't really interest me. I like using the Amiga's hardware and it is my intention to write games that use it like back in the day!
