Are you trying to make a Castlevania fangame? I've been trying to make one for 12 years and my coder keeps abandoning the project. Anyway, I've used Game Maker, MMF2, and Construct 2. MMF2 and Construct 2 are pretty good. Game Maker was ok, but I was using a really early build from way back in the day. They're probably a lot better now.
