Yeah I tried getting the game to a playable state to have some of my friends play test it but it just wasn't ready in time. I kept playing it thinking "man this is pretty easy, maybe I'll up the difficulty a bit" only to see my friends play it and get destroyed on some of the levels. You're actually able to shoot upwards in the game to get those pesky ceiling enemies but I hadn't explained it at all and lot of people didn't know they could do that. I had a tutorial level planned out but alas, those deadlines really creep up on you huh?
For the bosses I really should've touched up on the difficulty, the scorpion boss goes zero to one hundred real fast if he decides do keep spawning in drones. Thank you for playing though! I think when I can update the game I'm going to smooth out the difficulty a bit and add a little tutorial section before you're thrown into the craziness of the game.
