Good
I really like the color palette.
It’s a solid Brick Breaker–style clone, and that’s not a bad thing at all.
I like how the blocks change colors and have a nice animation when you hit them.
The overall theme is really well done and consistent.
Improvements
I would have liked to see a few more power-ups. Maybe something that makes the ball do cooler things, spawns two balls, or adds an extra platform. Just a small extra mechanic like that could make it even more fun.
The font could have been something more CRT-style to better match the aesthetic.
It might also be nice if the score were displayed inside the game screen itself instead of outside it.
On the laptop you have to zoom out to get the game playable
Check out my game if you have time. I’d love to hear what you think!
