I enjoyed this from the moment it started (great music). It was genuinely unpredictable, exciting, fun and made me smile the whole time I played- bravo!
Brilliant! The humour added so much to it. That final one was like a boss, lol. I tutor maths part-time and might have to get my students to play this game to practice their arithmetic.
Haha yeah I was unsure about allowing the player to hit themselves. Initially the bullets had a longer lifetime on screen and it was way too difficult. And yes, if you shoot an enemy that is of the wrong 'color' (or number, they're color coded) it will spawn another one rather than destroying it.
Haha, yeah I must admit I didn't put much thought into the color scheme, and I definitely need to learn more about color theory. Thanks very much for playing!
