Forgot about Tactical Breach Wizards, would definitely recommend. Superhot is great, superhot in VR is amazing.

How small indie do you mean, like one person teams or teams of 5 ok?

• Dyson sphere project, is a great factory game in development for ages and one of my favourites by a 5 person Chinese team.
• Rift breaker by a small Polish group is like a cross between Diablo and Tower defence factory builder lite
• Criticality, is a fun incremental game that will keep you occupied for a few days, hit neutrons to create a chain reaction, basically bubble wrap
• “Lost wiki Kozlovka”, is a very unique find the clue by reading Wikipedia articles in early 90’s internet only about 2 hours long, highly recommended.
• Take a look at the “secret of weapstone demo”, DnD in hand drawn black and white
• Alan’s automation workshop, is good before it gets too hard it you like programming challenges, try the demo first
• Silicon dreams, is like a physiological interrogation, you are trying to determine if the people are human or malfunctioning Androids, again there is a demo
• Horripilant, is an interesting auto batteler, again with demo
• Terraformental, is an incremental text adventure where you build skills to survive a time loop
• A dark forest, was entertaining, currently free demo
• Cleared hot, it’s basically desert strike helicopter gunship game
• Tower wizard, fun for a few hours
• Little rocket lab, like factorio but you take over a town and it’s cute
  Kids recommend “look outside,” and “mouthwashing”, lobotomy corporation, lethal company,
• The signal state, another programming type game
  My youngest recommends "rainworld’ like a 2d dark souls
  That’s my list from the last couple of months. I tend to search demos by genre and wish list things that get my attention. No idea how any of them works under Linux

EDIT: had to fix up the formatting on mobile.
Edit 2: went through my review and added:

• “Town to city” like cities skyline but fun and cute
• IXION, nice little confined space city building game
• The crust, heaps of potential but waiting for them to finish it
• Shapez and Shapez 2, fun little puzzle factory games.
• Sandustry is more fun than it has any reason to e
• cataclismo
• space rock breaker, a cross between pachinco and asteroids

older games,

• TIS-100, like assembler but more limited
• papers please, love this one, love the aesthetic. If you don’t want to play it watch the live action video homage ~10 minutes

I’ve ignored VR games, let me know if you want those too.

Thanks for sharing
You’re awesome
If PC mark still available I’ll put my hand up
If not, you’re still awesome :D
