Thanks for the Linux version :)
Pretty sweet so far! Great job!
I'm pretty sure you know all of these but will mention them just in case:
- On PC you could map Esc for the pause menu as well
- Adding a pause menu button somewhere at the top will be good for mobile (I don't think hiding in PC is needed - personal preference there)
- When you pause, the player forwards movement is halted but not the vertical one. If you are mid-jump, it falls down
- The pause menu is visible behind the win/lose screen
- On the 3rd level I'm not sure if will want to turn the camera when switching to the diagonal paths
- Possibly add a backwards bounce when you hit a platform head on to avoid the player getting stuck. Right now this could be gameplay mechanic depending on how you look at it :D
The gameplay is really relaxing! Really nicely done!
