Love the idea! Some notes I took during testing:
- Some music and sound effects (even from a music library) would go a long way
- Shift for down is unfortunate considering it is mostly used for faster or up in other games
- Enter is not a great key for start because you need to take your hand off the mouse
- Movement feels quite floaty because of the slow acceleration and the tilting
- Wall jump feels pretty good!
- Love the ragdolling after hitting the goal
- Maybe add rotation and scaling to the editor with different costs for operations?
