I reached the end last night. The final boss did make me ask myself why I was even playing this game.
But I also spent a little more time just wandering around and trying to find more chests. That aspect of the game remains enjoyable even as some other aspects disappoint.
Overall, I’ve spent a lot of time fighting with the physics. Sometimes because I thought I had a solution but it didn’t quite work, and other times because even the intended solution seemed a little broken. (Which is not necessarily a bad thing. I like messiness in independent games.)
I suppose I remain ambivalent, this being one of those cases where I care about the bad only because I see a lot of good and a lot of potential.
