Congrats on completing the game! Here are some remarks.

The good

• The game features simple and intuitive controls and has a clear challenge and a goal.
• It is visually obvious where you’re not supposed to step (spikes) and derives into tactical gameplay
• The game has all elements and feels complete
• UI seems ok, although I believe there’s a better way to present the collectible item progress

Area of improvement

• The controls need to feel snappier, I feel like I don’t have enough control of my player character
• It’s hard to detect good items from the bad ones due to the overpixelated graphics
• The challenge feels too random, leading to unfair situations regardless of the skill
• Music needs some better progression/melody

If you follow these guidelines, you will essentially have a fun minigame, it currently feels too unfair, leading to getting boring quickly.
