I'm hitting space and nothing is happening except the shape's wiggle in place. I've tried holding it, hitting it quickly, tapping it... I either need instructions or it's not working for me. :/
I had a feeling I was missing something. I'd say pretend (or know) your users are idiots in the future and make sure all necessary instructions are stated.
good shit, man. Game's great. Simple idea, but well executed and pretty fun. Add a scoreboard and I think you could sell this to the public.
