get hit once you DIE!!!!!!!!!!!!! (click flag to try again) - arrow keys to move - x to skip upgrades - collect gems from enemies - you only have to aim drone and katana (drone aims opposite to your cursor, katana aims toward your cursor) - upgrade descriptions don't state everything that the upgrade does - the dots on the bottom of the upgrade tells you the level of the upgrade - space to pause
please tell me if there is anything rong that I need to change. and thanks to @rat-violi for most of the game
