The story of Bug Killer

bug killer main level Recently I remembered that there was a game we made with my groupmates on the 3rd year of university (5 years ago!), and, guess what, it is still in my private git repo so I cloned and built it (surprisingly successfully).

What is subscription?

Subscription is a type of in-app purchase (IAP) that allows you to provide some services/content/features for a limited period of time. For example, full access to streaming service (Spotify, Netflix), ad-free access to piano tutorials (Piano 3D), access to a premium collection of photos or videos etc. The key point here is that users can buy subscriptions multiple times, that makes them a bit similar to consumable IAP. There are two types of subscriptions in AppStore: auto-renewable and non-renewing.
