It feels like this was planned from the beginning.
1. Get as many people to sub early on with promises of bi-weekly updates and then monthly updates
2. Cut the rewards in half when enough subs has been gained by dropping all the promises.
3. Only a fraction of supporters cancel their pledge due to sunk cost fallacy
4. $$$ Same profit for half the work
The way he was pushing so hard for people to sub and incentivized everyone to advertise the game on all platform with wishlisting and likes. Now you don't see much of that. Smells very fishy to me
