I seriously enjoyed this! I felt like I was locked in a WWII tank battle against Joanne from Marketing for a few minutes, I really did have to change my strategy and it was satisfying to finally defeat her. I love the sfx and the general vibe and genuinely think this could be a great full game with more time and polish.
I will say, once I got all of the lvl1 upgrades (particularly attack speed+projectile number) everything was all over, I was firing spit balls out of a machine gun and it was trivially easy. But that initial difficulty hump was fun to get past.
