Hello,
thank you for your detailed answer. I appreciate that.
1. No, there is no reason : ) It was a little bit rushed, and I wasn't sure about the coding part, so I decided to do it like this. But I will update is ASAP.
2. Yeah, I'll do that now.
3. I think jumping is normal. However, there might be a bug with the gameplay. If you could share a photo or a video so that I can see what's going on.
4. Press F. The snake explains it I think.
Again I thank you for your detailed comment.
