PS. Thanks for all the positive comments I'm getting. I'm definately planning to make a sequel with tons of new ideas, to continue the story.

Cool it, people. If something closely resembles a very popular game I think it's fair to say that it was on purpose. The author made an original game, but decided to give it a theme that is an obvious tribute to Portal. And the theme fits this type of game.

Paying tribute to a game does not point to a lack of creativity. Nobody said "Keep it original" when people made flash versions of Portal (and called it "portal flash" or something), or any replica of any game for that matter. I'm not saying that all the commentors are dumb, you are all allowed to have opinions, I just wanted to stick up for the author.

Great game.

Fun, challenging, and somewhat original. It resembles Portal a bit more than it should, but it was entertaining nonetheless.


Rated 4.5 / 5 stars

fun little game

I think this game was rather neat. Puzzles were fun.. but i was hoping there would be harder and more chanllenging lvls.

And to the jbgray guy below... like you said the plot wasnt necessary, YET you keep getting caught up with the plot. If you dont like it, then ignore it, or rather skip the intro part and turn off the sound. Yes we can skip it instead of just sitting there complaining about it.

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.


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.

I think the graphics and gameplay are great. what ruined it for me is the portal stuff. Keep it original
