Thanks you so much for playing our game, and your kind words. We do plan on making a commercial game out of this. We did our best to pack in as much content as we could into the 7 days. Hopefully we can expand on it a lot more in the coming months. Take a look at our devlog if you want to get an idea of how we did it:
