I like your game, It is fun, challenging, and requires some strategy especially in the higher levels.
I am privileged to have seen the development journey of this game. You are dedicated and a hard worker. The choice of the game design idea is great. Moreover, the things that you can buy with coins is a good addition.
I think you can add a mini-level in the beginning where players can be introduced to the basics especially the mid-air jump. It will also be good if players can buy things by the coin they get from this mini-level so that they are introduced to market and the items there.
Congratulation on completing the game and the graduation!
