Hi Mike,
Thanks for checking it out and giving me your impressions. So far you're the first. I'm glad I changed it to offer it in the UK.
My son Joe did most of the graphics, which are better than anything I could do. I think he was going for a sort of retro look. Although both of us can code fairly well, unfortunately neither one of us is an accomplished artist. I'm not even a good critic, I can't even envision what would make them look better (shinier, more 3d looking?). When we put a demo version out on itch.io a few months back, others commented on the graphics too so you're not alone.
Thanks again,
Phil
