I'm also gonna take a look at the demo,see how much it has developed since January.Also,something to mention.You said that the full version will cost money and that it will be available to buy on your site and on itch.io but what about Steam?It would be nice if the game was on greenlight.
Edit: Completely scratch off of what I've just said.Forgot that Steam Greenlight has been removed and has been replaced with Steam Direct(which is basically almost the same but without the voting system of the community)
Edit #2: Game runs moderate on full settings on:
AMD A6-4400M APU with Radeon(tm) HD Graphics
AMD Radeon HD 7670M
Video Card #2
AMD Radeon HD 7520G + HD 7670M Dual Graphics
Microsoft Windows 10 (build 15063), 64-bit
