Thanks for organizing this Devtober 2019 Jam! Like most  "indie" game developers I struggle with making fun games with very limited resources. However, making a game within a limited time is a good motivation for me, so that is why I joined this jam.

It is tempting to start from a working game and then extend it, and this is what I did too. In the book "Foundation Game Design with HTML5 and Javascript" by Rex van der Spuy I found the code for a game called Time Bomb Scroll, which is a template game where you have to collect all the bombs in a limited time. I want to make a pirate puzzle game starting from this.

My pirate puzzle game should be about a pirate collecting coins, solving puzzles and fighting various enemies. So far the game is only about collecting coins, while building bridges between different islands by pushing stones into the water. Later I will add enemies and weapons. Graphically it is very simple and there is no sound or music. The goal is to make a puzzle game, that also contains some action, and is "fun", whatever that means. The game so far can be found here: Blood Island

Crabs have invaded the island. Also there is a sword that can be picked up, but is useless. Palm trees are now growing on the island. Still, the game is not very entertaining. Probably the map should be larger, and a sword that can be wielded would not be bad. 

To produce some time pressure green goo was added. Now the player has to keep on moving to avoid being caught up or blocked by the goo. The goo is growing exponentially, at least in the beginning when it is not blocked by walls etc.

I have been working on a second level, which is larger. This new level is also harder, but unfortunately there is no restart possibility yet (sorry). The sword is working at last, and the green goo has been animated to make it more visually interesting.
