Great job on figuring out the controls! Unfortunately, I can't seem to replicate the glitch you've experienced with the spikes in my coding platform or on this version. I'm really sorry that you've run into this issue and I hope to find out what is causing this soon. Thank you for playing and I hope that you will be able to see the full game once this has been resolved.
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!
