Effective July 30th 2021, Bug Attack! on Steam will be changing price to a super affordable cost of free!
This is not a F2P model, nothing about the game is changing, no microtransactions, no pay to win, no loot boxes, nothing of the sort.
There will be a DLC available called the "Support the Dev Pack". It is completely optional, and simply contains a file with some neat info about the game and a heartfelt thank you.
This choice was pretty simple. The game was never profitable to begin with, so I'd just like for as many people to enjoy it as possible, while still possibly being able to earn a few bucks for the work.
