Had fun with this one, even if it didn't run smoothly on my rig. I'm a complete sucker for the sense of speed and momentum you get from this kind of movement, specially with how high you can jump and the fast movement.
UI could be improved, there's not a lot of contrast, specially since the level itself is quite bright. Tying the spawn of the hourglass to the level up was confusing at first, and considering the speed at which you run out of time, let's just say I died a lot, hehehe. Projectile speed should be faster IMO, specially to deal with the flying drones.
I would really like to see this getting developed further. With some optimization and a few other levels and weapons, this could really shine. Awesome entry, well done!
