I like the pixel art atmosphere. The style is commendable.
There was no sound on my browser (Microsoft Edge). I'm sure it'll be fixed in the next iteration.
I didn't understand what the avatar should do to go through the guard on level one... 😅 Perhaps it would be helpful to introduce the controls or what to do at that point. I tried pushing the rock towards the guard to block the guard, and tried running quickly to the entrance before the guard blocks the way, but was still slightly confused.
Nice vibes!
