I've got a new batch! Actually, I have about two, so I'm mixing and matching them in two different lists. This is the first one

Fan favourite Luig is back at it with Swamp and Luig by Dialobic
   
Find Luig! In a swamp? If you've been following this thread, you've found Luig before. Charming, clever and accessible. You can find each Luig in about five minutes or less, expect about ten to fifteen minutes of play.

The Tiny Escape by  Stefano "ProcioneSx" Trivellin
   
It keeps things basic, but does the basics really well. About half an hour with plenty of puzzles. The puzzle design is good, even though it sticks to well-trodden ground. It manages to capture a sense of dynamism you don't always get in adventure games.

Road to Nowhere by  turturi
   
Well-written surreal fantasy adventure, or maybe more of a visual novel with a couple of simple puzzles. About twenty minutes.
 
Beanman Gets His Cool Back on Steam (self-produced) 
   
A walking sim with some light quest-work, odd humour and a cheesy but satisfying musical score. Different endings! Completing the entire game will take you about an hour or so.
 
Model Human by Zapzap
   
One of the three latest MAGS entries - and I suspect this will be the winner. It's a comedy romp with a couple of puzzle-shaped shenanigans. The developer(s) ran out of time and had to make certain concessions - I think one or two bugs and typos have been fixed in the latest version and it ran without issues for me. There is one timed puzzle that gave me some trouble, even when I knew how to read the signal clues. Regardless of any of its limitations, the game is complete, playable and enjoyable - if you can deal with some scatalogical humour. Took me about fifteen minutes. There's a little quiz at the end where you get to determine the fate of humanity.


Second list!

A Night at Moka Efti: A Babylon Berlin Story on Steam

Wild Boar came up with this one. It takes a lot of notes from Disco Elyisium, but ditches the RPG elements (and some of the depth) to deliver a modern adventure game. The voice acting is in German, but the writing and UI can be set to English. About two hours of gameplay and high (German tv studio) budget production values.

edit: usually I recommend games I've tested start to finish - I haven't finished this game and I'm going by Wild Boar and the general concensus on this one.

Leaving Han D. by Laywelin
   
This game depicts the emotional journey of leaving a partner. A poetic reflection of a deeply human experience. It's about five minutes, the puzzles are pretty easy and I found it moving and beautiful.

It's pouring down there by elcococlot
   
A bleak horror game. The animations are pretty good. The puzzles are decent, nothing too complicated. There is some pixel hunting involved - the lack of colour doesn't help in this regard. The objects are named when you hover over them. One hotspot only becomes accessible when you know about it. Somewhat unfriendly design, fitting the atmosphere of the game. It's about fifteen to twenty minutes - I played it twice, to see if there was another ending. I didn't find it - and I think the way the game "resolves" itself is part of the narrative.

Play Exit Five in Browser by Lasse Müller
   
A short, conceptual game, straight from the Twilight Zone. It's basically one anomaly-based puzzle, but it has some cool effects that make it more engaging and exciting than the sum of its parts.

edit: link in the AGS games database, in case you want to leave a rating/review.

Thank you for the list and your hard work!

Your feedback is always appreciated! And I was suddenly reminded of

Miles to go before I sleep by Emma Gundersen
   

Minimalist adventure/walking simulator about love and moving on. I played it in a dream-like state. This would've been labeled an art game around the start of this century. Like the accompanying atonal music, it's jagged and evocative. It may not be for everyone, but if it clicks, it does something to you. I'm trying to find the second ending, but I think the whole game is about twenty to forty minutes.

Thanks for the updates BobVP. There are some incredible looking art available here. Road to Nowhere specifically.

Thanks again BobVP, for continuing to keep us updated on interesting Freeware games. I will have to add that A Night at Moka Efti: A Babylon Berlin Story game to my Steam library.

I played the developer elcococlot's previous game The Watchtower because I liked the art, but I ended up getting stuck because it had a quick time event and I didn't realize it. It seems like this one also has some other unintuitive design choices as well.

Later this month we should be getting some more interesting freeware games as part of the  $110 Adventure Game Challenge. There's been some nice games in past competitions so I'm looking forward to playing a few this year.

Thanks for checking them out Joshua and PopPunkParty!
