As stated in other games, I am terrible with platform games, but I tried for a bit.
People talk about snipers in the volcano, but I found more weird that I should be interested in collecting money while my legs are going to burn in a few seconds!
Aside for that, it's good for people that like to challenge themselves in endless jumping.
Adding at least a few sounds, like jump, shoot, collecting coins and a catching background music, might help to play once more time ;-)
Keep polishing it, you will get a nice time waster game :-)
