Thank you so much! You have a great set of ideas here and I am definitely definitely definitely (Yes three times) going to be putting more time and love into this concept. I think I could make a whole game out of this.
Some of the stuff I had partly working was COOP and some camera dynamism going on. Building up some storyline to go with it, adding some different roles you might do, some degree of Airship customisation or so. It could really blossom I feel.
Thank you very much RedstoneEngine and congratulations on your notable entry as well! I had a lot of fun with it and I immediately got this Portal-esque feeling from it, like being in some crazy test-chamber. (For anyone perusing these comment sections, I really recommend checking it out as well.)
