Clocked over 100 hours, right to "not true" ending. Will be playing more when time allows it.
The game is fine on Wii U with exception of towns and stables (at some angles). I think devs made the decision to compromise those areas since there's no combat there. But it still sucks. Kokiri and kakariko are the worst offenders. Gerudo, Goron and Hateno are better in that department.
In the overworld there are places when framerate dips for second and then gets back up to 30 fps. There are also places where framerate dips and stays at ~20/25, fewer but still.
In terms of combat it's all fine. People are saying that finishing blows on some mobs (bokoblins I believie?) hangs the game for a sec. To be honest i thought it was intentional as it bring more punch if that make sense. Feels like bullet time kinda.
In this 100 hours there was one time when it clearly choked for about 2-3 sec in combat. Encountered 2 bugs. One was when fighting giant skeleton, which punch me through the ground to the out of bounds area. The second i'm not sure it was a bug. Got struck 2 times by the lighting on a clear day, but it's possible that was a lynel i didn't see. Come to think of it there was also one instance when the music stuck in endless loop but it was very specific. Killed that big desert monster right before blood moon kicked in. And it didn't respawn, while the battle music still played. Fast travel fixed it though.
But other than that it was very pleasant ride. No blood moon bugs, no save corruption, game didn't crash once, Wii U didn't catch on fire.
It's not perfect by any means, hope they iron out those framedrops in the future. But it does not detract from the experiencie which is the main important thing here. It doesn't get annoying to the point "that's it i'm done..."
