I'll check out that suggestion soon. If you want my two cents, as long as your game is unique in any sort of way, you shouldn't feel like you're ripping someone else's game off. You put the effort into making it sure! Best of luck with whatever your future endeavours may be, I'll keep an eye out for any of your other projects!
Also I found the Apocalypse mode by accident while playing around on my own time. Clever, and difficult to get!
