Being completely honest I didn't enjoy it. I'm sorry, however below is my feedback if you're game below and what I think needs to be improved:
Unfortunately a lot of the art is very clashing and it's difficult to tell what's in the foreground and background. I also believe that the might be an error on the difficulty as collisions seem to happen when the player is very far away from the object that kills them. The coins also go up by 100 was that intentional? It is very jarring to see you immediately die, re spawn and music reset all in the same scene.
I do think it can be improved with time, work and as you grow as a developer!
