This is my comment as a player.
1. The starting area is quite confusing because it took me quite some time to start the game. I dont know that I need to hold the attack button to start.
2. I like the animation and the SFX. The animation is smooth and SFX is really great at conveying the game.
3. Im not sure how the game represent the theme.
4. I know this is just a minigame/a demo, but I wish It has more clear goals and objectives.
5. I think it has good potential if can develop more levels and puzzles.
