“Tiny Brains is a small game that is best played with friends. If you play it solo, you'll find the puzzles a bit boring, the horde missions awkward and the get-the-ball-to-the-other-side puzzles annoying. The graphics…”
“Tiny Brains is an excellent co-op puzzle game that I think anyone can enjoy. It's not portal, but it's still an excellent game, what really makes this game shine is when you play it with a bunch of friends- and that's…”
“Well... it's an 100min game, most fun with 3-4 players, it's quite buggy to, nothing major gamingbreaking, but you will probably still die becuase of it. If this is worth 100min for this price, sure. Otherwise this is…”

“Got this on sale for $1 and for that price it is completely worth it. It's not a long game but it is enough. You have a short story mode (2.5 hours) and then you can do some puzzles and other things. I played coop and…”
“Bought this on a whim and holy crap, it's a hilariously cute co-op that you can have a blast playing with friends or family. Definite must buy for gamer parents with gamer kids as it's a great mix of the mad cap,…”

“Great co-op fun. Laughs to be had, rewarding challenges to be completed. Reminicient of co-op portal. Very fun, but you should get 1-3 friends to join you.”
“Me and a friend played and it took us like 2 hrs to do the campaign. It was a nice short game that was actually quite fun. The puzzle mechanics and switching characters between the two of us was sometimes a challenge…”
“This is one of the best games to play with a friend! It's light-hearted and funny, has a cute art style and can be quite challenging at times. I highly reccomend it, and make sure to grab a copy for your friend too!”

“Though hampered by the occasional bout of unpredictably frustrating physics, Tiny Brains is unique and creative enough that you forget to care. It's clear that the game was designed with multiplayer at the forefront, as playing solo is possible but significantly less rewarding.…”
— a player, Steam review · 13 hrs played“Great game for a one-time local-coop play through. Mechanics do get old and repetitive, but main story is only ~2 hours. The bottom line is you should get this game if: -You have access to "friends" for local coop -Are okay with about 2.5 hours of gameplay -And most importantly,…”
