Pretty cool
A decent shooter with a pretty cool leveling system and awesome graphics. There's one glaring error that prevents me from giving it a solid 10, though (aside from some lag, which is forgivable): the powerups, namely the final suit. The dash was SUCH a problem; it wound up making me die a bunch of times when fighting the final boss (who I also died against because of the two second lag at the beginning of the fight, along with other things that shouldn't have made me fall during that battle but did) because I'd tap the 'right' key and he'd go running off the platform. It didn't do anything, except help me escape those awful "Yellow God" tentacle dashing things.
You did a great job with this, but if you're going to include dashing, make it do something, and make it easier to control.
