Def intense, WITH THat slow build omg XD. gotta give it thaT.
*Feedback: (might include SpOILERS)
Great build and tense atmosphere, GREAT VISUALS EVEN FOR THE GAME PAGE. Worked pretty well for grabbing attention. the only thing that i think might make it slightly better than it already is, i mean the existing one is a job well done too. dont get me wrong.
MAYBE having TO LOOK FOR MORE JERry FUEL CANS around the house THAN JUST ONE, maybe 5, your pick. For ur 1st game, this is mad good! Though this slight touch would add more fun and tension to the already existing one XD.
The knocks though, brilliant idea for a puzzle. I did mistake them for morse code XD. Morse code too could be an interesting element for a future project. there's a l0t more in store for ya, and you prolly already know it too.
Overall, enjoyed it ALOT! Keep it up and wish you the best on your future projects! lets see you bring more interesting games to life ;)
