Controls of the game are arrow keys as noted in the description. I think wasd somewhat works as well but it was not intended therefore probably won't be fully functional. Spacebar is not a key used in this game. One thing that was not explained at all but is intended is the cap on the bug and fertilizer counter. bug counter is limited to 3 and fertilizer to 2 to prevent stacking them up extremely high and growing the flower from its smallest state to largest in an instant. Sorry for not explaining that part anywhere
