Loved this game so much! I kept playing in endless until I had unlocked everything. Very well polished, the music is good, love the SFX and the button shake when hovering. I think it really only lacks some difficulty, but I like it this way too as a relaxing game. I never ran out of money and I could always buy all of the upgrades when they were offered if I'd unlocked the tier. Great job, definitely one of my favorites!
