Hey fellow jammer! First off, I love the mechanics and needing to be really careful on what block you are stepping on, especially on the later levels. For me, enjoyment takes the cake here in terms of the 5 criteria. There are two notable points I got really frustrated with, one is the lack of reset, forcing me to go through all the levels again once I softlock myself because I ran out of blocks, it is increasing frustrating when you get to the later levels and have to play the entire game again to get back to where you were. The other thing is your font in the level scene. That font does not look good when zoomed in/expanded that much.
Ending with a positive note, it is rather impressive that you managed all the assets alone! That's very impressive for a first-time jammer !!
