This entry is really cool ! I liked the concept with the day/night cycle as an upgrade/fight cycle. I found it quite weird to have a bow with reduced visibility, but it becomes better as you buy light upgrades. The labyrinth was a cool setup, it would be super cool if it changed/ you got teleported every night randomly to force the player to not stay at the same place I think. The visuals for the characters are all super pretty too, it would be cool if the others visuals matched those of the characters (the walls and the bow).
Anyway, I really liked it and there is already a lot of content for a game made in a week, good job !
