We're keeping both versions (itch.io and App Lab) up to date. The itch.io version it's the latest one uploaded, and future updates will come to both platforms as well.
This still isn't ideal, as the game gets forgotten, hidden away in the Unknown Sources menu, and without the nice icon display.
Having it installed via App Lab makes it show up in the game menus like any other and imo is a much more professional appearance.
It doesn't matter how up to date the Unknown Sources version is if I rarely go in there, especially with App Lab now starting to offer a wider range of games. Tbh, I'd probably have put more than a cursory few games into Crisis VRigade if it wasn't so hidden.
It's the sort of game my wife excels at in the arcade, but she's not going to rummage round an odd backwater text menu when there are more accessible games to choose.
Honestly, I'm slightly surprised you weren't among the first to offer App Lab keys given the reputation of your game.
I tried this game when you originally offered it for free on sidequest. I later bought it on itch.io to offer my support of your game. The applab version of the game has several advantages over side loading it in addition to being listed along with the other apps. Updates are able to be installed automatically in the applab version. I would instead need to check here regularly to see if there is an update and then go through the hassle of hooking my quest up to my PC, downloading and sideloading.
Offering applab keys to those of us that supported you by buying your game when it was offered for free would be a great way to say thank you. Based on the process that I went through to get applab keys for two other itch.io games, it seemed like it was set up for them to easily do.
