I'd love to double the number of levels, add an enemy of some sort - a sentry maybe, which lies dormant until triggered. When triggered it'll chase the player down. A final upgrade will aid the player towards the end - or I'll settle with a fast reloading ******** which is already in the game, but not used as a weapon.
Another enemy (or the sentry) could also scan the surrounding area with a laser which hits the invisible walls. The beam rotates and therefore there'll always be a safe area where the player can move. If the laser hits the player the player dies and the level restarts.
The game is also in dire need of a proper ending.
Anyway grab it here:
