I'm very impressed with how much you were able to put together for your first ever game project!
Now, I won't sugarcoat this - the game's not great. Most of the art looks pretty rough, there's no audio, the controls are floaty and some of the mechanics don't make sense (some coins can't be collected, only pushed around? i touched a coin and teleported to a different level where the camera was zoomed in?)
Regardless, I think you should be proud of what you accomplished here. Putting a game together like this that actually functions - with no prior game development knowledge or coding knowledge in general - is incredible!
