Welcome back! I really liked the claw machine guardian, that was really well done. The end screen doggo was adorable.
I feel like the items should probably get picked up automatically, or at least fall down when you break a block that's in the air.
Small bug, you're able to break two blocks at the same time if you aim between them.
Digging a staircase up is pretty hard due to needing to be directly adjacent to the block you're trying to break. Not sure if a terraria-esque way would work better though.
The blanket often spawns pretty close to the surface, it'd be good if it was limited to the lower half of the playable area or something.
