This is great. Love the clean and colourful aesthetic, and we seem to share an affinity for silly walks!

It's the small details that really make this one shine, like the wacky arms interacting with the environment dynamically, and the character clumsily climbing over all the props. In most games, being able to walk up and down the sides of a tent would be immersion breaking, but here it just makes me smile. And that idle sad face gets me every damn time. Clearly this little guy is struggling with an addiction. While it can feel like wasted effort, these are the kinds of things that turn a tech demo into a memorable experience.

Aside from minor camera issues, one real critique I have is on how the music is implemented. It's interesting that the tempo increases and decreases based on the character's movement speed, but the end result is a bit offputting to the ear. Since the dungeon is quite precarious to navigate, most of the player's time is spent moving about slowly or bumping into walls, with bursts of speed to avoid traps. This means the music is always dramatically shifting from super slow to full speed. I like the idea behind it, which is that the character wants to be running around hoarding items and not standing still. I think an improvement would be to have music with a constant tempo, but multiple channels -- perhaps just a muffled bass line when standing still, and fade in drums and melody as the movement speed increases. 

Overall, excellent work!
