Finally! The first Friking Shark level is playable.
There are some missing details and a lot of aspects to improve, but the hardest work (most of it modeling and texturing) is already done.
I want to thank Diego Sánchez for his invaluable support, in a direct way by modeling the coolest Level Boss ever :) and in an indirect way by pushing me to try some techniques new to me (like occlusion and normal maps).
I'll try to have a Windows demo release and upload the project to Google Code by the end of the week. The Linux release will surely take some time (due to my ignorance in deploying Linux software).
