In Stuffing Fields it might be worth considering replacing the corner posts that appear for example here
, and here
with another form of block? You may find it more aethetically pleasing. Otherwise it looks like a good level just a little bare.
Thwomp Dungeon Descent has a very nice palette! Good music choice too. I actually don't have much to say about this one because overall it seems like a pretty cool level that would be fun to play.
Para-Beetles. That's the review.
