This is a really interesting concept; I love two characters games. I have some suggestions:
- Maybe make it so one character is controlled with WASD, the other with the arrow keys, so you can control them both at the same time.
- The lose sound scared my soul out of me. Lower that down haha
- The coin's life bar is at the center of my screen instead of the right side. You probably did the bars with the "Unity Canvas", so probably you just forgot to set the coin's bar pivot to the top left side in the rect transform. Should be an easy fix.
- There is some walljump glitchness in the game. Perhaps consider creating a "Physics Material 2D" in Unity and setting its friction and bounciness to 0 and then attaching that onto the 2 characters in the Unity inspector; that might fix your problem.
Pretty sweet game overall, keep developing it, I'd love to play a full version of it with more features :thumbsup:
