This game is... awesome! It's very polished and well on its way to being something truly special. I did however encounter a few glitches when playing the online version. The most common one was that when I selected a build card that needed to be placed in the world and then tried to select a different card, the block was instead built under the card I was trying to select, wasting both the card and the energy points. In the tutorial, I built a path to go forward and then was prompted to use the rewind, which undid my build but didn't give me my cards back, so that was a little annoying because it was right when I was starting to figure out how to play. Lastly, I had a glitch when I selected a level in which the level started at the top of the screen, but the map screen didn't fully go away, effectively softlocking me. I've included screenshots:

You can see the level at the very top of the screen here.

And this is the level I selected that caused it to happen, the glowing card/relic square just above the one with the white box.

I love the design for the pawn, by the way. They're fun and have cool little details to them, like how they kick their legs when they're sitting or how they transform into a UFO at the end of each level. Also, are the legs supposed to look kind of like bellbottoms or am I imagining that? It might be that the reversal pose looks a little like they're dancing.
