I like how you inplemented the theme, it fits pretty well with the gameplay. However, the gameplay isn't very smooth for now. I encountered a bug where the tutorial wouldn't show in the main menu, so I played it blind. I was not very sure about the mechanics and goal of this game, and there are some technical aspects you guys could definitely improve on:
- Make the background music loop, the music sounds great, let's not have silence during the gameplay.
- Have a quit game function.
- Manually spawning the blocks seemed redundant, have it spawn automatically instead.
Overall, great job! Congrats on completing the game!
