Unfortunately, we ran out of time to implement the one feature that would have brought the theme into the picture. So you will have to imagine with me until I can update the game in the future. :)
Blobby is flammable and the plan is to have a growing fire hazard chasing him through the levels as his slime trails ignite and cause a sense of urgency. Also, the spiky glass bits are supposed to be hazards for Blobby. We were just too ambitious and ran out of time.
Thank you for checking it out and for the feedback.
