Absolutely beautiful presentation. The Kenney sprites are very good, but the way you used them and added animations was great.
My main question is about enemies not respawning. It made it feel like a battle of attrition. Is it possible to clear the game without dying? It felt like in some rooms all I could do was kill one enemy, respawn, walk back, and repeat until the room was clear. If that's not the case, then having the enemies respawn would help communicate that I'm doing it wrong.
Some of the items were really interesting, especially the belt, shoes, shield, and helmet.
The Gnostic theming was... interesting? I feel like it didn't particularly correspond to the themes of the jam, but it made for an unusual experience.
