Arrow keys. wasd, and space if you prefer. Diamonds give health, yellow outlined give extra, stalactites hurt you, watch out for the bigger ones. Changed a lot from Bashtons original game, play it yourself to see.
Bashton made the og in STEM class with me, most of the code and stuff is his, I redid/changed a lot of sprites. Credit to @Negative_Monochrome for the custom variable display. Comment any bugs!
