In Ugh! you basically play the role of a prehistoric taxi driver. You have a little craft that functions on a principle similar to that of a helicopter. You have to transport people between various platforms and stops, while being careful not to damage your craft and avoid all kinds of pesky creatures that will make your job more difficult.
You can also pick up rocks and bombard trees for extra time, or disable creatures for a moment. The game itself has a very positive "atmosphere" and gives a very friendly impression so its also suitable for small kids. Every time you complete a certain level, you get a secret code that you can later use so that you don't have to start from the beginning. Another treat that this game offers is two-player mode that is very entertaining.
Even though the basic concept is simple, the game is able to keep you occupied for hours since the missions are pretty diverse. Sound effects are very soft and relaxing so I have no objections to that. The only drawback to the game is that I found it impossible to complete one level, so that's why I give it a 4/5 mark!
