The concept here is great, but I don't think the scoring is actually working. No matter what I do, including glitching into the ceiling so they climb as high as possible, the score is still 0. I think what would actually help a lot is having a 75/25 split between physics objects and non-movable objects. That would make it more of a platforming game where you need to jump as high as possible. Because all of the objects are physics-based, they fly around randomly and don't let you stand on them for more than a second or two before the spiders go up that high. Here's what it looked like when I glitched the game. Haha.

Its a nice little game and I like the concept. The sound-design is nice, eventhough I think its missing some background music (but this is a 3 day game jam after all). In general its a good game and in my opinion an enjoyable experience!

The easiest way to describe this game is the lava floor. On my video card (which only works at 10% instead of 100%), it lags, also this game is very easy to use (you can complete all levels in 5 seconds)
