I recommend having a browser build for demos, as you are not selling a product, you are testing it. I like to think of marketing as king of the hill: When you are the vendor, you are the king on your game page, people want to play and buy it. When you are giving a free demo, the player is the king, you are asking for their short time and attention, so you need to make it as easy as possible. I can't download windows, but I will give the advice I can from the images/video: I think the art style is really nice, well defined. I think you might want to try and promote a more aggressive play style, as if I played this, I might find it easier to just run away and follow the coins. Maybe try making the police much faster than the player to force the player to find ways to crash them more often. I think you might want to have a more unique upgrade system. Maybe add some sort of mini game or another interaction to make it feel separate from the main gameplay; look at games like Pacific Drive and how they have more interaction built into the upgrades rather than just pressing a '+' button to watch a stat go up. Looks really cool and chaotic! Good luck and I hope I've been useful!
