The fact save points are basically nonexistent, separated by huge lengths of stage populated by really, really annoying enemies that are more frustrating than fun to fight kills the game for me.
The save points being basically from Africa to New Zealand apart wouldn't be so much of a problem if the breakable items in the game actually dropped healing consistently. For some inexplicable reason, they're randomized.
Plus the player's intangibility being the same length as the enemy, AND there's no indication on a majority of the enemies that they're intangible is also extremely frustrating. I've found myself in constant grab loops over and over because of this, and it's really, really annoying.
Couple that with the fact your attack now locks you in for an annoyingly long time, and also forces you to step forward with each swing, with enemies that are either way too tanky, come at you from odd angles or have absolutely no indication of what their going to do next, and the game just feels like crap to play because you get reset back to Africa when you're two steps from New Zealand because of one of several of the jank things above.
