The Wicked Father
"You play the unconscionable character of the title who has locked his family in the basement and flooded his 15 story (or 20 or however much room I have left in 4K) mansion. Life insurance + house insurance = PROFIT!!! Make your way to the top of the house to escape or you will die with them!"
Throughout 2011, Junosix updated the levels and fixed many bugs. He called the game finished but revisted it in 2012 to add difficulty settings and a reset function.
Hopefully some day this game will make it to a cartridge release!
