Hey there, quite a well polished short game! With a bit of lore hidden reminiscent of silent hill kind of games. Especially with the PS2-era graphics that I think worked splendidly in your favour!
Good:
The graphics are awesome, as I've mentioned. I think, whoever's in charge of graphics and the art direction, knows their thing well and created a great atmosphere. Great setting with good sound, atmosphere and music (or the lack thereof).
There is great build-up with (thank god) no jumpscares but very well-placed horror elements through changes in the background (most notably, the big eye(?) in the background after picking up the second item). I quite like the way you handle the horror elements in the game with its subtle nature, but was somewhat unsure of the final monster is basically just a guy that opens up to eat you. I think the monster design could do with a bit more horrific/gore nature. Maybe add some blood squelching sound everytime he walks, and make him walk slowly? Give him some gurgling growl noises and maybe maybe give him multiple heads, or hands, make him more monstrous. Just my opinion.
I LOVE how you integrated the UI into the game world, rather than having an 'interact' button on the screen, it's plastered on the game world instead. It makes it more seamless and immersive which I think is absolutely essential in a horror game! I would love to see you improve on this UI way more, to be more polished.
To improve:
The controls when inspecting objects are extremely wonky. The anchor points are not centered on the object so when you rotate them, they rotate about the pivot of the corner of the object. You also don't get anything interesting when inspecting the object, making it a redundant mechanic. For example, what if you could only get the pieces to fall off when looking at certain parts of the object from an angle.
Would love to see this expanded into like a 10-minute or 1 hour game! What a thrilling experience! In general, the horror set-ups are amazing! With great build-up throughout and small bits and pieces revealed to the player as they progress.
