I don’t see it here so I’ll mention Ty the Tasmanian Tiger! Really fun collectathon platformer. Played through the more recent remaster on PC and realized it’s very easy, but I spent a huge amount of time as a kid just running around the maps and hub area.
WindowKill - $4.99
The most clever bullet hell I’ve ever played, best experienced on mouse and keyboard.
Windosill - $2.99
More of an interactive art piece. Very short but I still think about it years later. (Some of their other stuff is available online for free and is similarly enjoyable)
Magic Wand - $3.99
Like a surreal, jumbled mess that seems to parody a badly translated JRPG. Another short and sweet experience.
HYPER DEMON - $14.99*
Like a nightmarish fever dream. If you like old school FPS mechanics like rocket jumping and bunnyhopping you’ll feel right at home. This one is a little difficult to show people gameplay of because it looks impossible to decipher, but when you’re actually playing it and really start to get entranced, it’s an experience like nothing else. The way it gives you a 360 fov is an incredible mechanic.
*(It’s also 40% off for ~40 hours as of this comment, making it $8.99)
Chicory: A Colorful Tale - $19.99
My favorite game of all time. Adorable puzzle game where you paint the world, with a story about what makes someone an artist. One thing I really like about this is the open ended way it lets you approach creative tasks; It’s up to you to decide how much you want to invest, there’s no scoring system to gamify the art portions, which is very in-line with the story to me.
Edit: Oh, and a great soundtrack by Lena Raine!
