Tribloos 2 is a fun casual management game where you guide a tribe of small hairy creatures on a quest to stop the storms threatening their island and build dozens upon dozens of houses wherever they go.
In each level there are various tasks that need to be completed, usually the gathering of certain resources or items as well as the construction of all the houses. To do this you send your tribloos from the main building to take care of business, wait for them to finish, make their way back and then send them to do the next thing.
It's a simple concept, and there isn't much of a challenge or pressure there. Levels are timed, but there's no penalty to taking your time, and I'd advise you just play things at your own pace.
The game slowly introduces new mechanics, like special headwear that helps you navigate the later environments more safely (like hardhats that save you from falling rocks in the caves). In the end there aren't any (positive) changes that truly shake up the core formula though, which isn't fatal to this otherwise neat little game.
The only frustrating thing in the game is the later levels attempting to add challenge in the form of environmental hazards. Especially the leaky pipes, which stops any passing tribloo and sends him/her/it back to the main building. This leads to some frustrating moments where you have to time sending your units out at exactly the right time, except you don't know when that time is since the travel time they take to reach the pipe is virtually impossible to estimate.
All in all this is a relaxing puzzle game. The flaws that are there are outweighed by its charm and the light-hearted story going on between levels.
It's not critical to have played the first game, which hasn't made its way to Steam yet, and it's a fun enough little game.
