Exactly my issue. These types of games from these types of devs drive us away from steam so we can support the devs and get away from drm. But without any sort of killer feature to bind us to the platform the increase in price just seems silly. Tax on a digital product for anyone outside America is also very poor taste.
I hope either the platform realizes the position its in in the market, or the dev realizes that the game is more valuable than the shenanigans we have to deal with when buying the game here.
I honestly love achievements as a tracker for my gaming progress, but if a game doesn't have any then I will get it drm free and give as much as I can to the devs, but I would have felt even better on this one had I been able to tip the dev directly.
