It's a good game, but if you have a good computer, the game goes way to fast and you cant react quick enough. I couldnt even get to the first upgrade after 20 minutes. 2/5
great game, really fun. :D
and @roomiller who said:
This game has a lot of flexibility in terms of future versions as well, such as collecting different colored keys to open different colored doors to access new parts of the map.
A+ my friend. :D
