Great idea, I dont know if you plan to do 2 sets of sprites again (one for facing each direction) but if yes, ic can be the most ambitious sprite sheet that I've seen.
I plan to return to MMF2 with baby steps, something can fail again MMF2 or IRL related, so I cant say Im the most reliable person, but one thing is for sure, I plan to release my engine for the community if I finish one (I've started one before but lost everything) since I've seen that the major problem for making fangames is a working engine. I've seen various kind of artists here and if the community join forces at sometime in the future, omg, it would rocks.
Also, Im quite a newbie in that area too.
