This is a 'made for kickstarter', junk game. The game raised enough money to be profitable before it was available, so it was released without content and doesn't do anything but look good on an advertisement. There is no talk about increasing the functionality or vocabulary of the game on the product website, and it's not even worth the small price on steam.
The entire game can be boiled down to this: Hear and/or read a word, and then click on the thing that the word is associated with.
I have nearly completed my first entire language pack in about two days (there's like 5 words I can't seem to locate). I don't feel like I've actually learned anything though. The 420 words available are not enough to order dinner, let alone take a vacation in a foreign land. This game does not teach a person how to begin to communicate in a new language, which is the only thing the game had to deliver after getting over twice the requested amount on kickstarter. They got their funding though, so the only news is that they intend to release more language packs.
-This game takes way too much video card effort for the type of game it is, and it will begin lagging to death after playing for an hour or so.
-Does not understand multiple monitors, so it tries to plaster the game centered on total composite screen (hit F11 to get windowed FS on main monitor)
-The spaceship mode is completely stupid, and is there simply for marketing purposes. It's the same as FPS mode, except you have to hold the mouse button for a while instead of doubleclicking, and you can't stop to aim (since you're flying). Some of the targets are tiny though.
-The game was designed so that new language packs could be made in a day, with fill-in-the-blanks labels and audio snippets, but little effort was made to do a good job. There is often two words for an item without an explanation for which word to use when. The spoken words are often poorly pronounced and with anomalous noise artifacts. I suspect they found their voice actors on craigslist.
-Sloppy positional audio often makes words hard to hear when it should really just be monaural (since you're effectively listening to a voice in your head).
-Stripped down settings and options. Doesn't even have volume control, and doesn't remember major settings (like window placement and windows audio mixer settings)
