The basic idea for the purchase option is that it will increase in the default price with every major release.

It started at $10 as a special introductory price and has increased by $1 with the release of 0.1 and now with the start of 0.2. Further version increases to 0.3, 0.4, etc will be met with similar $1 increases.

At least this is the plan.

This system ensures owners have access to all future versions of the game including the full 1.0 release regardless of when during development they purchased the game.

The next default (base) price increase will occur with the release version 0.3.XX.

Subscribing on Patreon/Subscribestar is still the best way to support the continued development of the project. This is for those who have no desire to upkeep subscriptions and want a one time purchase option.

Note: The increases apply to 0.x patches not 0.x.y
