What went well with my game is the fact that I created quite a difficult maze I learnt how to use some new tools and techniques and quite effectively and learning these new skills have given me plenty of other ideas on other games to create using the physics tool.
In my project I feel like I could have added more texture to my game to make it look better and add more things to do instead of the player just completing the maze by getting to the treasure chest and instead collect things at the same time.
