The diegetic tutorial is the best part and honestly the best tutorial I've seen in this jam. WASD and the arrow keys drawn on the floor of the first room, then a mouse drawn on the ground further in. You learn the controls just by walking, without a single text box. After playing a lot of entries with no tutorial at all, that care really stands out.
The core idea, that your score can be destroyed if you die, is classic push your luck and it fits the theme perfectly. The HUD has the red health bar, the score in gold digits and a DIFFICULTY: 1 indicator hinting at scaling. The purple dungeon with stone walls, chest, crates, columns and a bubbling gold fountain is well put together, and the hooded white faced character has a good silhouette. The pink and orange gradient title screen with the background noise has a nice arcade feel.
Where I got stuck. The game window is bigger than the browser view, so the left HUD is partly cut off, I could only read "IFFICULTY" instead of "DIFFICULTY". I also got snagged against a wall column and took a while to unstick, the collision feels a bit sticky. And I walked through two rooms without finding an enemy or managing to open the chest, so I never got to experience the risk and reward loop that's the whole point. Something like a "press X to open" prompt would fix that.
Good base and the best tutorial in the jam. Just fix the resolution.
