Very fun game! I really liked that the levels had a lot of animations so the world felt alive, like with torches, eyes popping up in holes, and so on. I suggest adjusting the sound balancing, so some of the sound effects become more obvious. For example, the flame sound when the player is near a torch is awesome, but I only noticed that much later in the game. There's also a chime when the level is completed, but I didn't notice that for a while.
About having new mechanics being introduced through an in-game tutorial of sorts, like having to use the mace on a snail that's blocking the player's path, so the player learns that the mace can be used to knock snails. I think the other one was to have solid / translucent blocks that are on a timer that disallows/allows the player to go past, and then having enemies turn translucent when they're dying, so the player understands they don't have to wait for the death animation to complete before moving on.
I got stuck on a puzzle for a while, and you gave the hint that I didn't have the requirement equipment for that puzzle yet. It would be nice to have some notification in-game that would let the player know, so they don't spend a long time trying to figure out a puzzle they can't solve yet. Mages of Mystralia had a good method of something you could interact with, and it would tell you if you had the required runes for a puzzle -- perhaps you can do something like that.
Similarly, having an in-game hint system would be great. Mages of Mystralia had that as well, and Tomb Raider also had Lara Croft giving hints after a while, both of which were very useful to help players get past puzzles when they get stuck for too long.
Overall, I enjoyed playing this game a lot, the puzzles were good, the mechanics were fun, and I never felt like a death was anything but my fault (by moving too slowly, pressing the wrong key, etc).
