I see potential, but the devils is in the details! A couple of quick suggestions:
- I could not see the life bar without full-screening. To fix it, set up the Unity game to 1024x768 and then adjust your UI (I can give you more info on how to do it)
- I could not figure out how to progress from the second level, I guess after I died I did not have the energy to jump?
- I would show how to play before the game plays, because the explanations and the obstacles were arriving at the same time and I could not read them before running into the obstacles
Keep it up!
