I think this game has potential, but it hasn't been fulfilled.
I would have loved to see some animations. Now the player looks kind of dead as he slides around. I liked the visuals otherwise, though.
The level design was intriguing, even though it felt pretty repetitive each level.
The shooting system was weird. There's no context at all as to why I can shoot tiny blocks of... drills(?) out of my mouth. The character should have had something to shoot with.
Encountering ghould was essentially a death sentence because the ghouls appeared very close to the character, making it very hard not to take damage. Dying at that point was very bad for my experience because I wouldn't want to run around the level again. There wasn't so much going on other than labyrinths and occasional annoying enemies. They were fun to explore the first time though.
Even though the music was a bit erratic, it went along well with the aesthetic of the game. The sounds for shooting were weird, not what I expected, but still pleasing.
Finally, I liked the art. Background and props all looked great. As I said the player could have used animations, and he looked kind of squished.
