Honestly this is pretty good for only one dev, I like the premise of it a lot. The character controller is very slide-y and it felt like I didn’t have very good control of the little guy but that’d be an easy fix if you polished this up in the future.
I do enjoy the gameplay loop of going through a door and doing the specific action required! I feel for the chests it would be better if as soon as you open one that leads to a door it locks off the other chests that open the other doors, otherwise it feels like there’s no real reason for the choice to choose in the first place? I found with the interactions with the skulls and bones I had to be running into/over them to pick them up and then running into the front of the pedestals to place them which felt really janky, so if you’re doing that with collisions even just making the collision boxes bigger could probably help with that.
There’s tons of potential here for this to be a fun puzzle game though overall and it’d be interesting to see how you expand on it if you choose to! :)
