When building this game, I made the below goals for this game:
1. Hyper casual game
2. Continuous game flow
3. Difficult enough to make the game session short
4. Single hand control
5. Important assets to be Pixel art
6. Use actual music to replicate 80's synth sound style but not 8bit soundtrack which may affect the ear when using an earphone
7. Simple enough to be used without hints
Well, with the above goals, I've limited myself to quite an extent, and I need some feedback to make this game more interesting.
