This is my first time publishing stuff to Steam, so news might be slow and things might be rough around the edges as I get my bearings. Anyway, the demo is officially out! You can actually go to the store page and download the game, and I think that's pretty neat.
Also, there are some features that really need to be added, such as indicators for when you've lost (whatever caused you to lose should flash, so when a 16 runs out, it flashes, or when an 8 is overpowered, it flashes) and saving/loading solutions.
Other than that, the demo has everything you need, so get to it!
