Some questions came up on Steam regarding launch and funding
and Portalarium responded insinuating the cash shop is the only money driving development. They go on to say no one is being forced to buy from their add-on store even though in the same paragraph they suggest that if people don't buy from the add-on store then the game won't ever be finished.
Topic at hand is "When is Release". We are currently in Early Access
with launch coming up very soon (we will announce more of these details
later this year).
The reason some things (not the majority by any
stretch) are in the store is to ensure we can continue to develop and
eventually finish the game. If we don't do that, then the game will
never be finished. No one is forced to buy those items, so it is
entirely up to you.
