It looks very polished - Well done!! Keep up the great work.
Some feedback:
- Fullscreen doesn't appear to be working. When I tried it just fullscreened, but the main screen remained the same size. So this made it a bit harder to play, as my screen looks quite small
- I would have loved a bit more tutorial on what I was meant to be doing. I saw the text in the description, "Drag the slots into the player's grid to build chains. Then hit end turn," but I still wasn't really clear what this meant.
- For the stats increase on the player end, blue is a bit hard to read, so something more legible would be great!
