Bacteriophage! I enjoyed the art, music, and sound fx. I think because the UI was having issues, I had a hard time understanding what was being upgraded, so I just took the approach of "this round costs 100 per upgrade, so I'll just wait until I have 500 and upgrade all 5 at one time." I realized I could just hold the mouse down instead of repetitively clicking late, but it definitely made the end game more enjoyable. Nice job!
