Just wait till the 0.35 comes out because itch works in a weird way for example right now vers 0.25 is 5$ if you pay 5$ now you can get it BUT when the 0.35 comes out if the dev decided to increase the price up you would have to buy once again but if the new version is still 5$ you should be able to download normally
Note: this is only a problem on itch go to their patreon if you want the 0.26 and not risk paying extra when the 0.35 comes out
