Overall the game is really cool, effects, buildings, art, animations because all those was made in 72 hours! But at the same time, crafting games really need more stuff, like items variety and gameplay freedom to make the player feel encaged to play, but I understand making this in 72 hours is just impossible, you already did a lot, so good luck in developing this game! Hope I'll see it on steam with co-op option once:). Great job
