Meh
It's not terrible, but the art is mediocre, the level design is quite repetitive and it rips of Portal in quite a few ways.
Reviews for "Invertion"
poor physics annoying voice acting decent puzzles
some levels were simple to solve but very difficult to play through due to the slide physics on boxes. I might do the same action 40 times in a row to have a box slide the way I wanted it to one time (thereby finishing the level).
The voices were very, very annoying. I had to turn sound off. (music was fine)
very nice game!
cute lil' game but a bit boring if you play it longer.
to the guy below me. i played both parts of "give up robot" and it isn't like this game. not even a bit.
Less than the average
-1 The woman doing the role of Glados did a terrible job
-1 The controls are too slippery, i feel like i'm in an ice stage of a game, during ALL the game
-1 The stages were all too easy, without increase in difficulty
-1 This "illusion" mechanic is over-saturated, as well as that "sad robot" theme
Fun mechanic hampered by myriad annoyances
So the splitting thing, while not completely original, was employed to very good effect. This was, for the most part, a nice little platformer with decent graphics and (if you ignore the script--we'll come to that) decent voice acting. The controls were presented well enough too.
BUT.
First, the intro sequence. It was slow, the script was cliched and contrived, and the text effect (scanning to the end of the line, waiting for the voice actor to catch up, then skipping ahead again) was really awkward and distracting. To be honest, you could have just left it out or replaced it with a couple of lines, because there was no need for a deep plot.
Second, and I say this as someone who loves Portal: the "being tested by a crazy computer" trope is really, really overdone. Part of the reason GLaDOS was so compelling was because she was unique. The first few games to copy it were amusing, but now the waves are just ripples and there's nothing left to ride. Tina (I assume she did the voice acting for your AI) did a really good job, but was shackled with a painfully derivative character.
Third, oh God the music. Perhaps this is subjective, but after several levels I'd had enough and had to turn it off. Endless loops of harsh, grating electronica are very tiring on my ears. YMMV.
Perfection is achieved not when there is nothing to add, but when there is nothing to take away. There was a great game here, but it was let down by unnecessary additions. I know this is a pretty negative review, but there was talent here, and I look forward to seeing where you go from here.
