UPDATE: Fixed an error with the saving system. Your level and secrets should be stored now (hopefully).
WARNING: Will lag heavily on slower computers. Use the quality control in the bottom corner. If that doesn't work, either live with it or get a better computer.
For the AG Halloween contest. Sorry about the poo menu; it was rushed for a deadline. Sorry about the large file size; it's as optimised as it's gonna get.
Movement - Left or A; Right or D
Jump - Up or W
Attack - Down, Space or S
Collect coins in each level. 250 coins will give you an extra life. Hearts boost health. In some levels you'll need to morph into your demonic form to get through - collect three tokens to activate the gate, then walk through it to transform.
Plenty of secrets available if you collect the right number of coins or get through levels fast enough.
