Made the next video
You found a BETA Unit! Excellent!
There's a special prize for defeating all of them across the game, but progress defeating them saves even when the game is quit. This means if you miss one in one run, you can try again in another.
There's also one for collecting all of the batteries in one run, which is more difficult as far as exploration, but at least the batteries don't fight you back like the BETAs do.
All in all, great video! We love it!
