When you start playing and think "hmm, let's explore a bit". Two minutes later you fight a crab wearing glasses, you backtrack a bit and become a dino, completing the game faster than 4 minutes O_O
Very nice idea and overall well executed. Two flaws in my opinion are:
1) The dark holes are really hard to see, could use some clarity
2) It seems really awkward the way dark holes affect your movement, the first time they are introduced you are warned to not get close to them as they draw you close, but it seems as if you are at a certain range away from them you start moving weird and if you get close to them it's less bad.
Miss miss miss-->trial and error trainning-->you level up some more-->miss miss die-->STRESS MVP (at this point you lose your sanity at the pace of stress bar)-->combat trainning works!-->miss in next dungeon (does it work? you wonder)
(let's be honest, if you got the last achievement like I did you're probably a masochist, but damn it felt SO good when you got it)
