Call of Bitcoin is a side scrolling 2D platformer with two modes of play, normal and arena. The normal mode is just like any other platformer with the aim of getting to the end of the platform without falling into a trap or getting killed by the NPC's and to collect all the bitcoins present. Once accomplished you can move to the next level of which there are 50. There are four arena modes, where you have to survive the onslaught of several NPC's within the arena. You can pick up a gun in this mode to kill the NPC's and there's an extra life, but you have to work quickly otherwise you get swamped by the enemies. Personally I wasn't able to survive the Arena mode for more than several seconds as all the NPC's rush you as soon as you start the level and you have barely enough time to pick up the provided rifle, which is aimed using the mouse pointer.

Movement and action keys can be seen in one of the images below. The standard mode is reasonably challenging. When you walk over a question mark, a message pops up on a big screen, the first one tells you what keys to use in game. Once you get used to the controls its okay. The first image below that shows a level is the arena made. You can see the number of NPC's you have to content with. As they all drop to the bottom together I found it impossible to get onto one of the platforms. I assume the arena mode is just a survival mode where you have to survive as long as possible? in the normal levels, you can punch your adversaries to kill them using the action key. Apart from the spiked pits there are also gun emplacements that shoot frequently, so watch out when on any particular level as you may find a bullet heading straight for you. you can jump over these.

You can see a couple of in game videos of game play HERE and HERE.
