Thank you so much for your feedback! As this is still only a prototype and we ran out of time near the end, unfortunately some features got the short end of the dev stick, the skill tree being one of them. We'll try our best to improve the movement as that is the core game mechanic, and we'll be adding the functionality for the skill tree in our next iteration. As for some of the levels being completed already, that was intentional: This is only a prototype and the level the player is started on is a later level so that all the gameplay mechanics and abilities could be experienced by the judges (or whoever is interested in playing). In later iterations, we will start the player off on the first level with very basic mechanics so they can get the hang of it and from there each level will add mechanics/skills until all of them have been learned/experienced. Again, thanks for the feedback, I understand how this could be confusing, so we will definitely try to improve on it in later iterations! :D
