Well, I wasn't really sure what to make of this.
The graphics/art are ok in places, but mostly seem out of place. Also, the tree looks like it has writing/stuff on it (was it taken from somewhere?) Controls feel mostly ok, but the player character just doesn't work for me. Player collision and animations seem off when you move around/jump etc. Not to mention the 10 minute task I had of trying to climb the vines (?) Apart from a short intro peice of music, there is barely any sound through what I played, but for the player grunts and noises, shooting sounds.
Moving around I had invisible collisions stopping me from going places, which is fair enough - but it may have been nicer to have actual 'visible' things blocking my path so I had a better idea of what it was, instead of just stopping dead - so I had a clearer view of where I was allowed to go.
After climbing the vine thing, and running a little more to the right, I climbed a pile of something, dropped the other side, passed a robot alien thing shooting at me, and then ran to the edge of a cliff. I assume this is as far as the game goes, as you just fall off and die? (when she falls off, she doesnt actually die - just lands off screen, as you can still hear the player noises).
So.. overall, while I've tried to be honest and give my view of what I played - I feel it needs alot more work as it is, in quite a lot of areas, otherwise I feel Mia is gonna be stuck on the strange planet forever.
I think 2 stars is about right - for the effort at least.
