“It's inoffensive and looks pretty nice. If I didn't have so many other games to play, I would get into this. Don't like some of the sound effects, but that's a small complaint in the grand scheme of things. There are…”

“Listen. The game is $2. I got it for free and I would have paid that. If you grew up playing 90s and early 2000s pc games, you've probably played something that felt just like this, jank and all. Be free, eat fruit, see…”

“Complete this game took me more hours than i expected. The levels are not as easy as it seems if you want to 3 stars them. The mechanics are well tought out but the animals are sometimes hard to pass without losing a…”

“One of the worst cave man games I've played for sure. Very ugly (can be fixed with DLSS5) and unsettling to behold and filled with evil beetles. Basic game mechanics don't work and it chooses to rely on physics puzzles…”
“This game is so, SO bad, i'm amazed, it's undescribeable, I got it for free, but I feel they need to pay me for all the brain damage this game caused me”
“While I have joined the 2.7% of players who have actually finished this game, at the time of writing, and also got all achievements, it's not that impressive when you realise thay only 6.3% of players have achieved the…”

“amazing game this game gave me good lines and I very enjoyed it and im very happy I met vnge boonga and his family i hate the animals this game because they attack me ;[ but amazing game hope this helps you”
“Game is bugged once it's level 8. Animal Hitboxes are all over the place, spikes are brutal and if you fail a level like level 8, there's a chance you will always fail that level even if you beat it.”

“This is mostly an amateur game. Graphics are ugly. There isn't enough contrast for the collectibles against the environment. In fact, there is no visual indication of anything being either interactive or decoration.…”
“this game is just super janky, lmao. weirdly enough you can master this game with 75 stars meaning you can skip like 6 stars which is like 2 whole levels. and also sure this is 2016, games at the time appartently still…”
“Horrible game with bad level design, unpleasant controls and infuriating mechanisms that neither make sense or are fun to master.”

“this game has some intense crackhouse vibes that your crack parents had back in 2004 and you are also addicted to crack. giving this away for free is like giving crack to everyone you know”
— a player, Steam review · 0 hrs played“Following Unga's quest to return to his family sparks the player's connection to their own family. It seeks to establish the core message of connection in a discrete way without being convoluted. This is where Caveman World: Mountains of Unga Boonga shines; audiences are hooked…”
