Is dangerous,Let's split up

Is my first PC game project. Inspired by Mega-Man. I love how Mega-Man has different themes for every level. But I don't like the weapon you get after the level. It feels bad if you get a weapon and it doesn't work for the next boss you fight. So I want the mechanic to bind with the level.

It only has one level. Don't really feel like it going well, so it is abandoned. 

Idea before abandoned

- Having one unique level mechanism for each level

  - like bouncing floor, reflecting projectile

- Having one unique player movement mechanism for a few levels/a chapter

  - like grappling gun, double jump
