Very simple, but very clever concept! The difficulty rises nicely and the first few levels teach you the core mechanics well. An undo button would be greatly appreciated as it can be quite frustrating to have to restart the game on a longer level when you get stuck. Other than that, with some audio and polishing in graphics this could be a very good game!

"Loading bar" that was a genious idea! Good level difficulty progression. Though there is suddenly a huge one.

This was a really fun puzzle! The difficult took a sharp jump for the last map, and it would have been nice if you could have some undos as I missclicked near the end and had to start over. Also, I thought the beggining was a loading screen until I realised I had to click right, and there could have been a bit more fanfare for when the game was finished.

I could really see this being a fun puzzle game, and it would probably be quite easy to generate a load of levels procedually with a walker! I'd love to see more from it!

At the beginning I thought the loading bar got stuck :D But then I figured it out. A nice and minimalist puzzle game
