I'd already made sixty second shooter before I played Beat Hazard.
The shameful truth is that Beat Hazard really does everything I was trying to do with sixty second shooter and more.
First of all - session length. Because Beat Hazard lets you choose your own songs to play along with, you can pick two minute songs and have nice short games.
Also, a big part of sixty second shooter is pressing your luck - "How long can I go without shooting guys, earning multipliers, so I can cash in later for more points?" and "How difficult can I make this for myself and still win?" Beat Hazard does that with its Daredevil bonuses - the longer you go without shooting the more multipliers you get. Though it helps to unlock stuff.
I bring it up, because it's in the Humble Bundle right now. Normally $4.50 (and Super Hexagon is like $3) so even an above average Humble Bundle buy is awesome ATM. (If you have your music in the cloud you actually have to bite the bullet and install the good twin stick shooter songs onto your device. I recommend anything by Teo Acosta and Abducted by Sharks, who did the music for sixty second shooter.)
So, there I go, hawking a competitor's wares. Worst salesperson ever. But if you have a Vita, sixty second shooter Deluxe is still the twin-stick shooter to get. Gamers who know the difference between good shit and bad shit, this is the house they come to. Now, my shit, I'll take the Pepsi challenge with that Super Stardust shit, any day of the fuckin' week.
