Descend into the unknown in Shroom and Gloom a first person, dungeon-crawling, deck-building tale of mushrooms and madness.
I ❤️ that game!
First time I played it, I did not expect much. I played a few runs, for a bit more than an hour, than removed it from my computer. But then, a few days later, I wished to play it again... And now I think I finally beat it!
The game has a great atmosphere, its artistic direction is very nice, and above all, the game mechanics are very well balanced! It reminded me of Slay the Spire on how it achieves the perfect balance to make you want to try it again one more time 😊
EDIT: Decks & Daggers is also pretty good, with also a deck-building/fighting gameplay

Against the Wall is a videogame in its prototype stage. It is set against the side of a wall that stretches infinitely in every direction. The player must travel up the wall by manipulating its bricks, pulling them partially out of the wall to create ledges and staircases using a magic wand.
Against the Wall was developed during the Ludum Dare #20
Il s'agit d'un jeu d'exploration-énigme à la 1ère personne pour Windows. Le développement du jeu semble abandonné, après avoir duré de 2011 à 2016, mais j'ai adoré tester ce prototype. L'univers est assez vide mais réserve une petite surprise. Arriver au bout de cette démo mettra votre patience à rude épreuve, mais j'ai personnellement adoré l'expérience
Ce jeu m'a un peu rappelé DUE de Rubeki

Crazy japanese FPS: 1 level + 1 bullet-hell boss, the game can be finished in less than 5min

IVOR is a fast-paced shooter set in a Norse-inspired world. Find brutal weapons and rip through your foes. Keep moving, as death comes swiftly to those who hesitate.
In this puzzle-platformer, each level is made up of 9 joined together rooms. Shift the columns and rows of the level to separate and rejoin the various rooms, to create new (and perilous) paths for your Mini-taur to reach the exit. Good luck!
Great short game! Only annoyance is the limited window resolution

We spent almost an entire afternoon on this game with a friend!
It's great. The visual remind me a bit of Ape Out.
The gameplay mixes skillful twin- stick platformer-shooter with crucial powerup choices.
Those choices balance the game and let players craft their own tactic for the match, by combining them.
Note: we initially played it with one player using a XBox controller, and the other keyboard + mouse, but that made the game very unbalanced. Better use 2 controllers.

Parody demake prototype of Gears of War, sort of like a gallery shooter.
It's very short (<10min) but I liked playing it with a friend!
A local two-player fighting game about swords, soul-theft, and everything in between.
A bit like Nidhogg, but with very basic visuals & game mechanics (slightly different than Nidhogg though, it's interesting) by the author of Ape Out, and free!

A short platformer by the amazing Frank Force.
It has an original gameplay / level transition based on a scan line, and some tricky level design!
APE OUT is a wildly intense and colorfully stylized smash ‘em up about primal escape, rhythmic violence, and frenetic jazz.
I really loved this game. It combines a great, original artistic direction, with a solid gameplay. The storytelling is subtle (everything is told through level design, no words), the music is captivating (its tempo matches the action), and the ~30 levels are challenging.
The game is short (a few hours), but really worthwhile!
Due to the game excellent core gameplay loop, I have spent way too many hours trying to beat the last extra level named Break In! 😅
Catty & Batty: The Spirit Guide is a casual couch co-op puzzle game, inspired by Lemmings and Tower Defense!
A lovely 2-players puzzle game, with pretty hand-drawn graphics!

Un jeu d'action-plates-formes en deux dimensions où l'on incarne un samouraï, un assassin à la mémoire vacillante dans les bas quartiers d'une mégalopole néo-noire, La Nouvelle Mecque. Il est question de violence à outrance, d'une mise en scène hypnotique, demandant au joueur de la réaction et de la rapidité d'improvisation.
Un excellent jeu, très inspiré d'Hotline Miami pour l'ambiance et une partie du gameplay. J'ai aussi trouvé que l'histoire et la narration rappelait la série Metal Gear Solid.
Un très bon court jeu coopératif pour 2 joueurs, nécessitant 2 ordinateurs, basé sur la résolution d'énigmes
