Great! And it's also great that what makes it futuristic in design makes it fast (made of some polygons with 3, 4 or 5 sides).One problem: too short without custom levels and no multiplayer. So 4.25/5, I will give it a 4. I want a sequel.
It looks like that you don't understand what I want to say (from the -1 rated comment when I wrote this): so: this is a good game, but a skill test or a part of brains test not an intelligence or logic test. That was the point of my comment. I actually like the minigames but not the "Are you the brainiest" part in the description. As the description says, you can test "different areas of your brain". I said that not all because it would be impossible in minigames. Sorry for the many comments.
Oh, math skills. Everyone will be laughing ath math, if it would be only calculation. OK, math sounds better, but THIS IS NOT MATH. Math is: algebra, geometry, probablity theory, etc. 2/5 because of the title and descripion, else 3.5/5. Sorry, you maybe think that this is unfair. But I like to say the truth, not a truth-like something that is not truth, but a common theory. Too common. Most people (sadly) think that.
Also, the memory test is not a memory, just a short term memory (is that the word in English? I'm Hungarian, so I don't know, if not, sorry). If it would "measure" long term memory (maybe it's not the English name of it, sorry), it would be more accurate that how good is your memory. If it would calculate all the 2 types, it would be the best. But the long term is not for a minigame, so this is good as a minigame BUT the keyboard you see needs to have a setting because I have a Hungarian keyboard and it's QWERTZ and when I type Y, I need to look at my keyboard because I think "hmm, Y and Z?" and I check it because I think "my memory or the illustration is bad?". So yes, that's a problem for me.
No. These are just some brain functions. This has no logic in it, becuase I guess it's not easy to "measure" it in a minigame. So if you score low, that doesn't always mean that you are stupid, maybe only slow/not accurate, for example. Also, if you score high, your logic can be absolutely zero. So as a conclusion, it can be an OK measurement but not for everything just for small, small possiblities of brain. I give it a 3/5 because this game "thinks" (or the creator) that it's the brain and nothing more. Otherwise good minigames, if I don't count this, I would give a 4/5.
It's not a huge problem that it's Spanish. There is no story to understand and instructions are explained in English in the description. I won't give 1/5 because of that. BUT I've seen this game many times on Kongregate. I don't know this is an example in an IDE/compiler/whatever or a just a copy-paste of a tutorial (http://www.strille.net/tutorials/snake/index.php), but it is just stolen. 1/5 and flagged.
