Hey congratz for completing the game, here's some advice to help you :
- The run is too slow in rapport of the jump
- The background had a weird effect, not a good idea to implement that
- Need a music
- The fireball goes through the walls and we see the light
- For the main menu, change the default background (grey isn't really nice)
- Miss some input in the floating info bubble
- The main character is maybe too blurred, maybe you forgot nearest pixel in the settings of the texture
- Some issue with the jump when you're against a wall
Unfortunately, there's not enough content to say I liked it, but keep improving and I hope you had fun doing it.
