Get magpie instead: https://github.com/Blinue/Magpie

Works much much better. I used to use this tool but it is outdated now.

Some old games I have tried with this get "fullscreened" but the UI doesn't and thus becomes useless as the mouse clicks on the wrong place.
Magpie does not have this problem and is FREE. So there is no reason to use this tool anymore.

What the heck? This tool is over priced for what it is. On top of that, the dude is charging $5 for DARK MODE? This is so stupid. Look, I begrudgingly dropped $7 on this tool to get the utility out of it. This is AFTER the dev raised the from from $2.99 to $7!! But then to see him try and cash grab more money for silly features like dark mode is so lame. And then has the gall to put up a $10 donation DLC. I get having a donation DLC if this was a $3 tool but I paid more for this than vampire survivors and I've dumped hundreds of hours into that game. Not only that, there's NO WAY a tool like this took more dev time and effort than a game like vampire survivors which I only paid, what, 2.99 for?!??

Don't buy this, use another tool or compile it from GitHub. There are also modded version out there that are pre-compiled. Just google reddit modded version of borderless gaming and you'll find the alternate git.
