Don't worry, all of our brains turned into jelly :p Also, this is the first time we're developing a puzzle game, and dealing with the level design. So, the hardness might be little bit our fault. Glad you liked it tho!
Haha I get what you mean, this game jam was tough for sure. And yeah we should've made some of them easier probably, check out the level walkthroughs if you need couple of ideas. Glad you enjoyed it!
