Caleb is passionate about coding and engineering. In his Gold Belt project, Helios Drift, you play as a spaceship and kill enemies to progress. Once you reach a score of 1000 you can choose a temporary upgrade. The score requirement increments by 100 every time you reach it. Once you reach a score of 3000 the boss of that level will spawn and if you defeat it then you win that level and can either choose to return to the hanger or continue playing. You can also buy permanent upgrades in the shop.
