I've nearly finished my first portal map and I'm getting close to the point where I need to implement the challenges (speed runs, least portals, fewest steps). I'm not the greatest portal player for those kinds of things, so my estimates would likely be off. However, if I could get one or two testers who are good at these things, that would help a ton is getting these estimates at a reasonable margin.

If you are willing and able to help out, please feel free to PM me and we'll get in touch.

Thanks for your time!
