Thanks! Yeah, if I had more time I would have done a tutorial level to show how the win condition works. But I think I had about 20-25 minutes left and only two levels, so I just did what I could to crank out something people could play and hoped for the best. :)
Glad to hear you like the audio. I was trying to improve on that since it was my lowest rating in all my other Trijam entries. I found two "splat" sounds I really liked and play them at different pitches and volumes. One splat for horizontal collisions, and the other for vertical. I change the volume based on the size of the blob - bigger blobs make louder splats. I wanted to increase the volume based on the speed at which they hit the wall or ground, but found that to be too complicated for the time allotted (at least for me). The pitch is random just to give it some variety.
