You guys made a nice little 2D platformer . The music and sound effects are really nice, but having some sliders to adjust it would be nice. I usually like the music a little quieter to enjoy the sound effects of the game.
I really like the animations for gamebert. Love to see him in motion 😎 The overall look of the game is OK, but the art style is not 100% matching. A Parallax effect for the background would have been nice.
The biggest problem that I have with the game are the controls. I have already seen that you seem to have a different experience between the editor and web build and I don't know what might be causing it. My first guess would be that Time.deltaTime (or Time.fixedDeltaTime) is missing somewhere which causes the difference. Would be interesting to see how a Windows build behaves.
Anyway, I'm not happy with your usage of forces to move your character around because it makes the movement very floaty/slippery. I would recommend changing to a velocity based movement with acceleration and deceleration to make the movement snappier and more responsive.
Small tip for your character collider: Add a Physics Material 2D with 0 friction (but only after changing to a velocity based system). This should resolve the issue with getting stuck on the walls when trying to jump 😉
