really nice game! especially clever that you start easy with the upper half and few moments later get the second half. action packed!
for me overall the best game i have seen here in this gamejam, played most of them.
especially in 3hours, respect!
you would get my award for gameplay, difficulty, controls, sound and artdirection
maybe a little bit "off topic" with "underneath us" but, the second half of the screen is technically "underneath" the upper half ;)
maybe create a android port of your game?
