Pretty fun, liked the intro sequence. Upgrading felt good, demo seemed a bit short. The area felt a bit barren when the crystals are the only thing to mine. Keep it up.
Yeah, I had a few more ground types + ores ready but I handled time badly at the end (turned out I had a bunch of web specific bugs to fix last day) so I didn't get the time to enable them before the deadline, sadly :<.
