This is an interesting little exercise. It really makes you appreciate the ability to "wait" for your enemies to move. I did notice a bug where the map quits rendering if you go far enough down the screen (on the Windows version), but otherwise it is a solid little, frustrating puzzler.
This is a great start on a technical level and I hope you continue building your engine into a full blown roguelike. I also really enjoy the Dev Log entries. I'm glad you quit lurking on the fringes and ascended with a completed 7DRL!
