There is little I can say about this game that would be a negative. The custom art was amazingly well done, the boss fights were interesting and varied, and the controls were spot on. The story was well done and I honestly can't believe it was done in time for the jam. This was a spectacular title.
Suggestion: Give the spider a health bar. It's frustrating (especially on the the slug boss) to ALMOST have it then lose because you got too close to a bad guy and took ONE hit)
