Uriel's Chasm 3: Gelshock

You wake up...the gelatinous, adrenochrome saturated subject of an ancient prophecy, formulated by a brotherhood of abandoned sentient machines; Machines stuck on the cusp of an evolutionary leap.

Be prepared to explore an eerie, rusting deep sea mining platform tangibly rendered and hand dithered in the restricted NES color palette .

Fight your way through original, turn based dice battles and white knuckle, "graze" based, bullet hell boss battles on your quest to find out what exactly happened when the crude oil grave of an ancient race was disturbed, over a hundred years ago.

Controls:

Arrow keys to move, spending your roll when it is your turn. (You can freely move in combat where your roll becomes the damage you deal).
Z -> does most of the work / activates graze in the bullet hell sections.
X -> is used to clear the screen in bullet hell, at the expense of one notch of charge.
Space -> zooms you out to the map screen
Esc -> brings up pause where there are options such as:
Q -> quit
R -> recap the mission
+/- -> volume
S/L -> save/ load
