Coin Cavern

Coin Cavern
Version 1.0
By: Joni Pääskynpää

What is this game?
------------------------
Coin Cavern is Spelunky-inspired procedurally generated precision platformer.

How to play?
----------------
Explore the caves, collect 10 silver coins and find the exit to the next level. There are totally 10 levels. Each level is procedurally generated and gets progressively harder. Caves are also fraught with many dangers. Watch out for spikes, lava pits, different enemies etc. 

Enemies might also drop some loot if you are lucky. If you spend too long in the caves ghost will appear and starts to hunt you down. One hit from the ghost and the run is over.

Its recommended that the game is played with game controller. Game was tested with Xbox360 controller, but should work with other controllers as well.

With Xbox controller the controls are as follows:
- Move left and right with analog stick
- Watch up and down: Hold up or down
- Jump: a
- Enter to the exit: x
- Pause: start

Controls for keyboard:
- Movement and look: arrow keys or wasd
- Jump: space
- Enter to the exit: enter
- Pause: esc

Since this is only a prototype concept, there is no real secrets in the game. Or is there?

My personal journey
--------------------------
I wanted to figure out how to make Spelunky-like generated levels and cave system so I came out with this simplified game idea. It was meant to be just quick attempt to try out if I can do some kind of generation. And here we are months later. Sure its not a full game, but I think this one has a potential to become something. What do you think?

This was also my first ever platformer so a lot new things to learn there. There are still issues present, but hey, its a prototype. Simple idea. And the generation works perfectly as I wanted it to be.
