Love this! I like how slow and helpless you feel when you're just the regular dude. Makes the transformation feel super good. That's just good game design right there!
I feel like the upgrade crystals could stick around a little longer. I can see why you wouldn't want them to stay available for too long, but just a bit longer might be the sweet spot. But I love all the upgrades, and the shooting feels super nice, too. Oh and the death screen is AMAZING!
Keep up the great work!
