From best to worst:
The Pony Factory : 3.5/5
David sure likes Doom 3 huh. It's simple but the atmosphere is very good.

Summer Night : 3.5/5
Really love the simplicity of it. It's minimalistic yet spooky.

Shatter : 3.5/5
Shame this one is so short because I adore the atmosphere.

Mr. Bucket Told Me To : 3/5
Solid art direction for a small game, also love the music. It's not perfect but it's still one of the most memorable games in the collection imo.

Hand of Doom : 3/5
It's a pretty charming attempt at recreating the mood of the early first person RPG. I didn't have an incredible time with it either but it's pretty good.

Outsiders : 2.5/5
For something that was made in 7 days, this looks impressive (even though it's probably a lot of asset packs). Looking for very small objects everywhere ends up becoming annoying though.

Don't Go Out : 2.5/5
I don't have a strong opinion on this one. I like the Clock Tower reference with the music but that's about it.

The Pay is Nice : 2/5
Interesting pitch, however it's a bit ugly and the ending is very abrupt even for a teaser.

Carthanc : 1.5/5
The idea of exploring an ancient temple like this is cool, but every challenges are awful platforming sequences.

Rotgut : 0.5/5
This one is utter garbage.
