Edti 10 Min But Gameplay Like 1HR.

Ended it in less than one hour, great game but to reach more than level 30 you have to pay them, there is ads after every level but its totally worth it

30 mins of tutorial tf but good game though

47 minutes of gameplay. 47 of immersive experience. Downside is you need Half Life 2 to play it. I'm using it for sandbox.
