Very cool game!
At first I didn't understand how the double jump mechanic worked (Needing to have and spend coins), but once I did I had a lot of fun! The graphics are very colorful and charming and the music is quite catchy!
And yes, Little Devil is very cute indeed! ❤️
If you were to expand on this game, I'd suggest to make it so that players don't lose their coins once they advance to the next level. I think it could add more strategy to the game, as one could try to save on coins when possible, and instead use them in a different context allowing getting through faster 🙂
