Nice work, especially for 1 day! I think the way you can sheath things is interesting. I imagined it kind of like driving a forklift while playing.
I think level 2 and level 3 are a bit too similar in difficulty and you don't need them both. Level 3 looks more difficult than it actually is -- I didn't use the loop in the lower-left at all. Maybe you were thinking that loop needs to be used and that's prepping us for a later level? If that's the case, you might want to rework it somehow so that the loop must be used.
I haven't tried to solve level 5 yet -- it looks like quite a daunting task.
Having said all that, I'm learning in my own game that puzzles can be pretty hard to design well. I haven't made any levels in my game that I'm happy with yet, so I haven't shared it yet.
