If you look for a fun and easy platformer I highly recommend this one, as you only have to collect money while you fall down, where you have the option to challenge yourself and avoid every obstacle for a better reward. Its like one of those bonus levels from super mario, but much more satisfying

Droppy is just one of my favourite easy platformers by a long shot. It's a fun short experience that continues to keep the player engaged without introducing any complex mechanics that the player has to learn, and the player is constantly collecting coins from the start to the end of the drop. It's also very replayable, I can easily imagine a large number of people playing it multiple times to see how high their score can get
