I really like the game,
I'd love it if there was a way to remove/replace tiles, or maybe undo the last tile placement.
With the tiles being in random order and without the possibility to see all tiles, it's a bit frustrating to have to do the entire level just because the one tile you need just never came in time
I didn't know the camera movement was a thing so an in-game gesture to the possibility would be nice, I also didn't know about rotating fields till a bit late.
I think if you add more levels, polish up a bit more (I'd love to see fight animations for example), and add a story to it, it could make for a complete game.
Good job!
