Impressive making procedural generation and basic survival in 3 hours, although the lack of control instructions in the game or the game page might throw a lot of people off.
After I filled my inventory with tools I found to way to drop them so I got stuck at stone tier unable to craft anything else, house included. Also, since I needed to press 1 through 9 in my keyboard to craft, I couldn't really craft stuff like the houses at 10 or 11 since those aren't keys
