The game is so fun that I played it for like an hour. The controls were a bit confusing at first, it took me some time to harvest until I clicked by chance one of the empty squares and then tried it. The enemy hitboxes were a little big, and sometimes my attack didn't work so I got hit a lot at first. Then after creating a fortress I had nothing else to do, every enemy that came close just died (it was satisfying to watch, though).
It was fun trying the different turrets and traps, and waiting for the right merchant to come by. I feel like I was getting soul essence way too fast and the enemies were too slow, but that would be hard to balance for different players.
