Hi, thank you for taking your time to write this review. Originally we had planned multiple boss fights and multiple areas but as it happens in game dev we ran out of time and only had time for one area and a very buggy boss and enemies. At first we were planning to use a dragon that comes down and burns the village but we didn't know (still not that much) how to do a cutscene in Unity.
The cave part is going to be redesigned from the tile palette to the actual level design. Also darkening the actual cave as we descend is a pretty cool idea.
For the cave due to time constraints we used a prebuilt tilemap and maybe that was the issue of the colliders. The technical side needs a lot more work to be done and that's what we're focusing on right now.
