Doesn't compel me to buy it
I feel for you guys in that Super Meatboy is a really, really hard act to follow and I'm not saying this is a bad game it just feels... meh. That's the best way to put it. It's just not exciting and you're main (and what looks like only) weapon is underpowered. I realize the shooting was based on Robotron/Smash TV but why can't I aim diagonally? The fire rate is too slow, the damage is minimal on even basic enemies with an upgrade and even that doesn't help too much. The spread of your fire is too spread out and you sometimes miss enemies an inch away. Plus the lack of variety in weapons, powerups not being well explained until you use them and once you use them it's rare to find another one like it.
The art and humor was right on the money, just as good as Meatboy. But the big problem is the lack of variety and the shooting being so underpowered. For all I know the variety issue is resolved in the full game but for what is supposed to be a teaser/shareware it doesn't inspire me to keep playing like good Shareware is supposed to. I mean, come on, even the flies take 3-4 hits to kill, that many hits to kill one annoying low-level enemy?
