Really love the idea of your game.
Brings back some memories of good ol' doom :)
I also really like your UI and the winking of "doomguy"
Gave me the chills! :P
If you delve into the files i'm pretty sure I named the character 'ice doom guy'. Glad you caught the inspiration.
I will build upon the UI. Was meant to have a fire ranged attack, and frost melee attack that would have feedback through the UI.
As well as more emotions based on being hit / powered up etc. 6 frames of animation was the quick option!
