Ok, so, I got the bug again. Only this time, it's after the cliff I had to jump over!
The second spikes? Ok, this is really weird then, because I've run the program through several times and honestly am unable to tell how to fix what you are experiencing. I think it may be a problem with the placing of the sprite I coded to allow you to continue. I could try see if I could rewrite the code to fix it. It might take a bit, but there's still time before the jam ends to I'll get to work on it as soon as possible!
