This was a good effort, well done. I think the platformer control felt a bit annoying since the movement was a bit floaty and the player didn't move with moving platforms. Have a look at coyote time - something that a lot of platformers use that really polishes the movement! I was a little dissapointed to see "blue mario". I'm an awful artist but it's always nice to see original artwork. I hope you enjoyed the jam and well done for completing your second game! will definitely check your other on out.
