Awesome game! Meets all the requirements for Nokia jam. Jump being J is a little weird for the timing, might have a better chance at it being Space bar, but realised you're creating this for a Nokia. :)
Thank you, other people had mentioned the space bar thing to. I actually had it set to space for most of testing, lol. I usually change it to J since the space bar can cause the page to jump sometimes if the window isn't clicked on directly. I should have set it to both since I still had keys to work with.
