- Make Fade In/out between level : use a black sprite with the behaviour "Fade"
- Make the player invulnerable for few second after hit
- Make a animation to show when demon hit you (screen border red during the second of immunity)
- Make a better HUD : a bar for the weapon image and name, a life bar etc...
- The sign "exit" is weird
- The hit box of demon is way to big
- Add new weapons, bonus and stuff
