I know it was a little early to do a full on review for the game BUT I wanted to share my thoughts since I had the time.
1. The customizable character sprites and the unique sprites themselves were very nice and were unique to the game! I just wished I could say the same about the tileset which felt very RTP. I know you're planning to update the game to have a more unique feel though and so far the sprites you have in the game hold some promise. Fingers crossed the tilesets get updated to match the sprites in the future!
2. I get it was a sandbox, which is very ambitious for a Game Jam game. Though, I kind of hoped my playthrough in the Knights of Atlas had more exposition so I had a bit more direction. I figured out I had to go all the way North to fight some goons though I came a little underprepared because I was walking mostly aimlessly and didn't know where exactly to go to equip myself and prepare for the fight.
3. Maps were sprawling and huge which is good for a Sandbox game, though my big rub is that the characters weren't quite as intractable as I had hoped. I also felt kind of squicked that the area to customize your character was a 'Womb Level' which made the imagery combined with the bodyless sprites that only have eyes and clothes to go by sort of creepy and insanely *yonic*. I usually try to save that sort of visceral imagery for somewhere near the end of the game. Although RTP, it was also my favorite part of the game because it was memorable.
Overall a VERY ambitious project that I hope gets further fleshed out. It would have helped also if there was a browser version instead of a simple Windows download but we can't really win them all.
