I've been back and forth with that project... I decided to not only make an engine, but a nice remake of Mega Man 2 (my favorite of the classic series right behing Mega Man 9) with a few tweaks from myself. Problem is, real life is always in the way, and I have more than one project going on at the same time. Maybe on summer vacation (end of the year for me) I'll have more time to update that project. I surely hope so!
Anyway, the link for the forum post is this (The game demo is on Scirra Arcade too, but it's too small). Thanks for caring!
