Here is my 2D metroidvania I've been working on for several months now. It has at least 1 hour of gameplay. What else to say but, here:
http://www.forgottenplanet.com/caillan/legendgarden.exe <-- Game file. This might get caught by some antivirus programs, so you'll need to make an exception or something.
http://www.forgottenplanet.com/caillan/lgsoundtrack.zip <-- This contains all the game's music. A few of these were made by RainbowCrash88, contact him/her if you want to use them. The rest were made by Esnipplee and myself. Those you can use however you like as long as you don't sell them.
The first person who gets to the moon and the first person who beats the Astel Aventad core will get a special mention in this thread.
