Thank you for your feedback BenChong :)
Yes, you need to complete rows like in tetris !
We didn't have time to make visual feedback but when you shoot blocks, the difficulty level increase and max to 5. Difficulty don't increase when you dash in a block. Also, you don't earn any score by shooting blocks
Your ideas are really good too, maybe in a future version !
You can find a less buggy version with a small tutorial on our itch if you are interested !
