Some criticisms I've seen: -The humor is simply not some people's cups of tea. The fact that it's rather in-your-face in Hotland doesn't really help. -The bullet hell segments are weak compared to actual bullet hell titles. -As mentioned already, some people find the game to be too preachy -The game recycles themes from an Earthbound hack that Toby worked on some years prior. As for myself, my biggest nitpick was how there were no large-scale puzzles in the game. It's a really solid game, ESPECIALLY given the circumstances (it was a crowdfunded title made on Game Maker, that was mostly made by one person).
