I really like the concept of this game. It has great potential if you continue developing and polishing it.
The first time I played, I didn’t read the tutorial and just used the keyboard. There was a plus sign in a circle at the center of the screen, and I thought I was supposed to protect it or that it might give extra points if I connected to it. Later, after reading the "How to Play" section, I realized it was actually the mouse pointer 😅
That said, this could actually be an interesting mechanic. adding special blocks that grant bonus points or need to be protected in some way.
I also think it would be awesome if you leaned into a roguelike style, with power-ups or upgrades unlocked after reaching certain milestones. Even something like a new color theme every few levels, kinda like This game
It could help to keep the experience feeling fresh.
