One of the main goals for a mobile game development company is to have a demo ready for download at the end of a successful development cycle.
A bulild that is always stable and playable can be extremely beneficial, especially when it comes to those unexpected and time-sensitive opportunities around partnerships and marketing. With indie development you may only get one chance at a possible publishing or marketing deal and it can be heartbreaking to have that opportunity slip through your fingers as a result of a build that isn’t playable.
Often time’s solo developers don’t have to regularly create builds for external purposes during pre-alpha development. The risk of this approach is that if at some point a working demo is needed, the developer may learn upon inspection their build is buggy, crashing or not even building. Avoid this scenario by striving for continuous quality through clean code check-ins that is thoroughly tested in advance.
