idk if i am just really good at clicking or what, but i felt like i was given a huge amount of time in between waves and was always extremely prepared for whatever was coming my way. i have a (bad) reputation for making games way too difficult, but i think i would have enjoyed being a little more punished by this one.
i actually used OBS to record my entire 3 hour development but youtube rejected it because i hadn't verified the account. now we're verified though and i would have loved to be able to see you code this one JMac. if it doesn't eat your processor / bandwidth too much you should capture and upload your next game development.
