I liked the game and it was very robust and polished. The art and sound design is great, I would play this longer if you had more content, I was looking forward to seeing which direction this is going. I've played stacklands for multiple playthroughs and didn't know about WitchHand haha, I'll check that out.
Only bug-ish issue I found is if you play in windowed mode, you can drag stuff outside the play area and lose them forever, and you might do that accidentally.
I would love to see you put your unique ideas on this, hopefully you'll continue working on it!
