Paradise Fort is a mysterious hybrid of tower defense and survival platforming. You guide a small fella, exploit the rescources found from the island you live on and fight against evil birds, among other threats. I tried to make the game help you to figure out how to do stuff, but it may still be a bit frustrating.

CONTROLS
Arrows - move, aim your pick-axe and towers
A - use (eat/build), open menu and cancel
S - jump
D - pickup/throw, confirm

Note that the enemies (apart from birds) begin to appear only when you have enough cannons. So take your time to learn stuff.

EDIT: Thanks for the bug reports! These will come in handy in the post-compo version.

EDIT 2: It seems that a lot of people have problems with using the build menu to build stuff. Open the menu with A, choose a 'designation' and build it. The rescources needed for whatever you're building is listed in the menu, so bring those rescources to the 'designation' and either use (A) or drop (Down + D) them in front of the designation. When all the required rescources are in the designation, the building is finished.
