Hey thanks for the comments.
Yeah it's a Jam so didn't have the time to do all the polish we wanted and it was a fairly ambitious concept. Thanks for the feedback , it's really helpful.
For anti-matter, there is a structure that actually takes lots of hydrogen to make it. So you need to increase your output as you go. But your right, a tutorial or some kind of pop up to make that clearer is something we would need to do if we wanted to take this project further.
Thanks again! All of this is very helpful. Help us contrast what works with what doesn't work.
