In the end, do what you think you'll enjoy, but even with some of the rough words from people, their knowledge is solid. You MUST fix that joystick orientation, or else you'll hate it. PaigeOliver nailed the solutions, as did others, and I learned a new way to do that, too, today. If you need help with graphics, I'm swamped, but I do that stuff.
I'm still fairly new to arcades, 1 1/2 years, though I became obsessed! The idea to post designs and ideas is smart, on paper, but there will always be jerks who will pick it apart. If you're prepared to take the valuable criticism, along with the positive and negative wordings, you'll be better off! That said, enjoy this arcade. It doesn't have to be your last, and with any creative design, you'll always think of something to add to it, or make it better... It's ok. just be sure to step back, appreciate your hard work, and then get in and USE IT! I spend time building, modding, etc and barely play.. but that's mostly because I need to finish my basement (walls, carpet, friends lol).
Keep posting your developments, please.
