Medieval Gear Solid
Positives:
+The mood was pretty cool in this game. I like the MGS series and it fun to hear the alert sfx again.
+the guard design looked really cool and inspired
+the use of the pixel filter was smart to get a snes look but stay first person. Looked like a less crusty DOOM
Suggestions:
>I think sfx for acquiring the key could be helpful alongside the text on the screen you provided. Like a "bling" sound.
>Not really sure how this was a loop other than the fact you back to the start each time you lose. Nothing really changed whether I won or lost.
>While I thought the filter was clever there's no substituting traditional pixel art. I think using something like crocotile or sprytile would help with the 3D 2D look.
Bugs:
>I ran into guards a couple of times and didn't lose. I think a trigger might be off. I had to run into the guard on purpose to trigger the loss.
Overall:
I thought it had great use of color and could play a full game in this style if it had combat or the like. I think it missed the theme and constraint but was inspired nonetheless. I look forward to seeing what you cook up next.
