Hi. Played for 2-3 hours, thanks for a great time! Found bugs: 1. Abilities 1-4 (bottom) are missing, even tho I upgraded them. 2. After level 70, it stopped giving me cards. The XP would go up tp level 30K something (under the turret) and then will restart from 0. No more cards. :(
Love the backgrounds change for each 20 levels. I would love some sounds, but the music is cool. The starbase looks too flat for my taste, but overal it's a great little game. 10/10 would play again.
