Yeah. Super Metroid and Megaman X games all have jump. Although, Super Metroid's wall jump it's different than yer game's. Super Metroid's wall jump it's exact and requires you to have timing to be able to do it right. This could affect people who are not skilled at games and just want to play casually. MMX wall jump it's much easier, it is kind of like yer game's wall jump. If you care that yer game appeals to everyone, you could have both wall jump options, but that'd quite a bit of work. Another thing is that you make it MMX like so everyone can play comfortably.
