Cyberspace is a fast-paced bullet-hell shoot-‘em-up created with Unity. You have to move, dodge, teleport, and shoot your way to the final boss. But to earn upgrades, you must first defeat the whole wave and then choose between a random selection.
Instead of making the experience gradually more difficult over time, the idea was (relating to the game jam topic) that the game should reward players if they complete a level successfully. So they can get the opportunity with every single attempt to use their knowledge about the enemy patterns and boss fights, but with even more powerful equipment.
