The production values look quite good. At first glance, it isn't apparent what the style of gameplay is. Having watched the whole video it looks like a 3D take on Marble Madness with jumping. One thing to keep in mind is that this game is cerebral. It's not going to appeal to low IQ gamers at all. It's also worth noting, itcho.io by itself does not seem to generate a great deal of organic exposure. I notice DevLog posts receiving a couple of dozen views. So if 0.1% of people who see a game would be interested in purchasing it, a thousand people need to be presented with the game for a single sale. There are seven billion people on the planet, so I don't think it's a matter of game quality, which appears well made, but of putting it in front of interested players.
