Hey guys, dev here. Apologies that you've hit something of a brick wall. When I saw the game was being speedrun, I had a feeling this would probably happen before long. Game was made in a week, heheh.
Ancient Keys DX is still seeing active development, but most of the public updates have been on my Twitter and Discord servers. I'm pretty bad about keeping all sources up to date, I apologize. That said, I feel pretty confident that DX will give you a lot more to chew on when it's eventually released!
Super Ancient Keys is currently on hold, however. I don't know what the ultimate fate of the game will be, but it's not cancelled just yet. I will need to start thinking about my indie projects one of these days, though.
Anyway, thank you for your enthusiasm for the game! Really ups the motivation.
