Anyway, what else… I've been playing the full version of Öoo. What I'll say is that it has the smuggest dead ends I've seen in any game ever. The sort of dead ends that level designers wax lyrical about years later. Genre-defining dead ends.
It's also a game that feels like it's trying to use the standard Metroidvania map screen to its maximum mechanical potential. Like it has a need to fully justify the exorbitance of a map screen after the game's predecessor (ElecHead) went perfectly well without it.
The degree to which this really is just "ElecHead 2" musically and mechanically is kind of cute, although the central mechanic is pretty distinct and (insofar as the demo) emphasies a lot more slow planning and tense execution.
