The is a really nice puzzle game! It's quite difficult, and even when I finally understand how the game works, I still die from silly mistakes or being reckless. But somehow it's so addicting that I just started another run right away.
I do have to say that one big issue for me with the game is that, the lack of any animation at all makes understanding the game quite difficult, and dying feels very sudden since you can't see how the enemy moves and touches you. I think something a simple as a moving square would suffice.
Any, this is really cool! Well done!
