Review for version [0.4.21] Contains spoilers.
Mecha Academy is, sadly unlike the title sugest, not about piloting Mechas or learning how to pilot one in academy in order to a war veteran help the effort in winning the war with an extra flavour of having datable girls and sex alongside, but a medicore porn focused game with a a bit edited and mixed story of Idiocracy and Pacific Rim in the background with a characters starting as nicely written, but becoming more and more retarded very fast with each and every word comming right out ot thier mouths.
So, the story stat's quite differently than the generic porn game. MC is actually dying due to lung cancer, as has no more than few months left to live and as he has no family, no friends beside few buddies in the field, they used him as a test subject to put him into stasis in order to slowy heal him over next 200 years. You would think it's just a some military bullshit talk just to cinvince MC in order to test this new technology on a lab rat to aid healing of troops in the Vietnam affected by the Agent Orange, so US can simply nuke charlies into submission and keep thier troops somewhat alive to keep the civilians happy and morale of the army high and MC was but a lucky one to survive in one pod that long and he's simply put back into service.
But nope. As you progress the story you are learning it was actually a deliberate ploy to deliver MC right where he was needed, so he can simply save the day by being the chosen one to become pilot of a Mecha. If not for the title I woudln't actually know about it, because in this whole timespan of few weeks (or rather months, but with time skips) you can actually witness MC fighting with renamed Kaiju three or four times and Mechas being mentiones maybe few times more.
Even though the characters and story were already going down the slope at this point I was able to bear it until that scene with Mai requesting to self-destruct her Mecha, while being inside said Mecha, and... surviving it to the point she made full recovery.
I hate dumbing characters and plot in order to move it forward, like punching that not-kaiju few times and calling it a day or not having any troops, partially charged Mecha or anti-not-kaiju bombers (mentioned later in the game) on stand-by to aid Mecha in combat, but making sacrifice of a character pointless by making survive it is even worst.
As I wrote about characters being nicely written at the start and quickly going down the slope. Sicientist turned out to really be a Jester, her girlfriend a cheating whore and doctor, or rather a nurse, turned out to be a rapist. After that Mei not-sacrifice, it just went straight down with every dialogue. Not so stupid veteran MC became, this time for real, a caveman and a commander of the facility MC was training became just as much retarded as the council being in charge of the military. To be honest, turning down that energy condom around Earth just for aliens to exterminate everyone would be actually an act of mercy.
At least characters are nice to look at. And MC has actually a man looking face instead of that of a 15-years old kid. But his body? A bit too much if you ask me.
As for sex scenes, I have rather mixed feeling about them. Some are nicely done, some not that much. Sometimes you have an animation, sometimes you have just static renders. Sometimes there are retarded dialogues and sometimes too much of weird close-ups on female faces instead od the action.
2 stars, just for the effort.
