I like it! I'm excited to see what features get added.
I don't know what direction you want to go with it, nadiakasper24, but in case you're looking for ideas:
-A little extra money given for the differently colored lines we reach
-Boosters, that can be used but then have a cooldown period
-Some other action to do (like dodging or shooting asteroids)
-Aesthetic customization options that cost ridiculous amounts of money, so there's some goals for us to go for
Good, simple. Maybe a little bit too simple, if anything, but it's a good little time killer.
I'd add more powerups if I were you. (Speed+, Size-, Screen Clear, etc)
And you could have points you earn, that you can spend on different colors for your background and dot, or something.
That's what I would need to give this 5 stars...but it's a solid 4 stars for now, and I like it a lot.
Sorry, I realize I made a lot of suggestions there, I just see potential. :)
When you get maxed, the stores should still do something. The armor shop gives a repair (perhaps overpriced, to use up the abundant $?), the weapon shop gives a boost (less than a divine edge, but still extra damage?)...or something like that.
