This is very cool, but a bit tricky to get started with--the fact that you can't tell which way a column or row moves at a glance meant that it took me a real long time to understand what the rules for moving them were, and it was pretty hard to understand what each of the spells available did/which could be cast on what type of target.
There's a lot of charm to a Cinco-Paus style "learn through trial and error" gameplay flow, but the game feels like it could use a touch more feedback as to why a thing did/didn't happen to make that work. Just little things like each spell icon having a sub-icon that shows what it can be cast on, or having the spell icons have names, or have them light up when you're moused over a valid tile. That said, once I got things figured out it was real fun!
