Hi,
I'm currently taking an edX course on game design (11.126x), which is frankly, stellar. Part of the assignments includes creating game prototypes and getting feedback from strangers.
Please try my prototype:
https://gameblox.org/play/6453/Disclaimer: It is, intentionally, a rough and ugly prototype. I want to know about the gameplay -- is it fun? Interesting? Boring? Too easy? Too hard?
Some caveats to keep in mind:
1) You can't press enter to submit your answer
2) You have to quickly erase your answer (it doesn't clear between rounds)
3) You can occasionally hit the button twice (for two points!). It's a race condition bug -- I can't fix it.
