This has potential. But I can't bring myself to actually play the current version. I don't want to tell the Devs how to do anything but dying meaning the game is kaput, a giant death hole at the end and no controls, the green squares on the menus instead of actually showing what is what. This is an issue. You want more supporters you have to give more. Close off the death hole and post the controls and fix the green square thing. And that alone will help you gain more. But to just have this being so bugged as a demo will make people think the entire game will be a buggy mess. This is just my opinion. It feels like a low effort cash grab being as jank as it is now. I am NOT saying thats what it is. But it feels like a very low effort demo. You want more support I suggest refraining from releasing super janky demos. No offense because honestly I love the idea of this game and what short time I did play makes me very hopeful. But the bugs made me want to never touch it again. So just saying maybe fix the bugs before releasing the demo.
To the Dev: Don't give up on this game. It has amazing potential. Just be careful what you choose to release as this is what is supposed to draw in more supporters. At the moment it just makes people frustrated.
