We started in 2019 because the tools we wanted did not exist, or stopped working a month after we paid for them. Both of ours are still here.
Every build we have sold is still maintained. When a game patches, the build is paused in the store until it is fixed, and the time you lose is added back to your subscription.
There is no outsourced help desk. Ask in the Discord and the person answering wrote the code.
Access lands on your account as soon as payment clears - no waiting for anyone. It runs on one computer at a time, and you move it to a new one yourself from the dashboard.
Six years of demos and patch responses, all public. Go and check.
