You are an unknown developer and you post paid only games without a demo version. This is not Steam. There is no buyers remorse, no try before you buy mechanic here.
And your descriptions are often not in English. Itch is an English speaking site.
Please i need opinios
Make a html5 export of your games and put it on the page. The games look like typical mini browser games. Not like paid games for download.
And do not put paid games on Itch with price of 1 $. Minimum pay price is already 1 $. Switch to pay what you want. People willing to pay you anything at all will already pay at least that amount.
And most people will not be willing to play your games for free to begin with. That's what the web version of the game is for. Needing to download even a demo version is a big hurdle.
