Lovely concept! It reminds me of the boardgame Labyrinth (https://boardgamegeek.com/boardgame/1219/labyrinth)
My first run I had it pretty easy. No encounters with any scorpions and could just win easily. So I was thinking about commenting about that.
But then my second run I trapped myself in a corner with a scorpion lurking around the corner - no way out. So I smiled.
And my third run I was swapping tiles like a mad man ... until a tile from the other side moved above me, with a scorpion that instantly killed me. With even a bigger smile as a result.
So very well made, love the game. Could use some more variation, maybe add some tutorial levels where you explain the pushing mechanic and then the enemy movement etc.
But overall great work!
