Some feedback for the gameplay:
- Right now, there is no synergy between the sonar ability and the jumping, so in essence it is a platformer. I suggest to make the scan have influence on the platforms you can stand on, so that you have to time it right, make it more so that the scanning is important rather than the jumping.
- The headbob does not add anything to the experience right now.
- I got lost at some point in the level, maybe help the player a little by showing where you have to go
