It's a neat idea, and I like the simple sprites and slightly eerie music. I'm afraid I failed to get the slimes onto the platforms though! I might need a hint, or a slightly smoother ramp up in difficulty XD
Oh NVM I finally figured it out! OK. So for people who are better at puzzle games than I am, I think this is a really nice effort. I did notice there were some issues when the window was a size it didn't expect (menu buttons not working, I think because it thought they were in a different position than where they actually were) but overall this is a slick entry with a lot of potential. Nice going!
