When I try to purchase your game from Itch, 20% tax is added for UK customers, that's $7.99 + 20% = $9.59, which pushes the UK price to £7.61
On Steam the price is fixed to £5.79 (which includes tax). I would much rather support Itch and purchase the game here, but how can it compete if the price is so much higher?
Also, Steam demand a bigger cut of the sales price, so it makes very little sense that the price is higher on Itch.
