This game is really such a creative, fun little find! The interactions between the characters are fun, the history we learn is interesting, but the BEST part of the game are the designs. You can tell each design was carefully thought out and lovingly made, while sticking to tropes that are meant to appeal. I loved every character, every bit of logic behind the design (the moth thing was so fun and cute!) and I really hope to see more passion projects in the future!

VERY cute & fun. i really really like most of the guys. i was sad that univac's cat & the offering bot didn't have any sprites, however...but all the art is SUPER good short & sweet. hot robots. i can't really pick a favorite they all had really cute moments but i loooove the dynamic of the binac twins & i really want to draw them...mark 3's exposed wires were also VERY DISTRACTING....(in a good way) edsac & edvac were also SOOO CUTE TOGETHER Q__Q the only thing is that some of the loops in the music were very noticeable & especially in mark 1's room the song felt way too short compared to the amount of time spent in that room...it got a bit grating, especially when the part where it loops is so obvious.

The Eniac room......... All jokes aside this game is a perfect mix of great humor and education on the history of these vintage computers! An absolutely delightful experience, and definitely worth checking out if you're interested by old tech. 1000/10 would highly recommend and I will now proceed to shove Edvac in a locker.

A fun way to trick people into learning about computer history. I liked the details they incorporated into each character's designs and personality 7.8/10

Hogwarts Legacy price history: where the floor really is

Our Hogwarts Legacy price history runs to 100 daily readings and a $3.99 median. Why the sub-dollar figure in search results is noise, and what to actually pay.

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.

Rust price: why the cheap keys vanished, and when to buy

The Rust price has two answers: an official one that barely moves, and a reseller one that sat in single digits for 95 days and then disappeared. Our record shows both.

Planet Zoo 2 price: which edition, and when it gets cheaper

Planet Zoo 2 is out today. The Planet Zoo 2 price splits two ways, the cheap pre-order keys stopped existing three weeks ago, and the original got dearer as the sequel landed.
