Thanks for the feedback and compliment - and good idea we'll be sure to add this when we develop it more.
And thanks for the compliment on the music selection. It was free however, and not created by us - you can find the link on the game's page
I agree with making it less difficult -I'll make sure to take into account any difficulty spikes in future game jams. I originally decided to make the second level harder because we did not have time to develop a third level and wanted something that would take more time, but perhaps we should've opted to remove some hazards here.
And when we develop this game more, i'll be sure to put wires between switches and the objects they effect to make it more obvious what they do -thank you for the feedback! Greatly appreciated.
Also the music was free - not composed by either of us. The link to the site we got it from is in our game page description.
