ATM I think I'll concentrate on the editor, making it very user-friendly. Designing levels for the original game would be cool. Not sure which freedom I'll have in the end, but I can definitely move all the monsters & bonuses & alter monster stamina and behaviour (I could make the frog jump and head to the exit, thing which is nowhere to be seen in the original).
On the other hand, the remake would have better graphics. The biggest work is to make the AI (that I have ported from Gods remake) work.
