Which indies did you discover and would love more people to know about? I’ll start: The Pale Beyond. Not sure if it’s a hidden gem tbh, but it’s such a good story rich game. I laughed, I cried and felt the characters struggles. If you like story rich games/ choices matter, check it out.
Phoenotopia: Awakening – an amazing metroidvania-related game. Relatively more popular than the other games I list, but is honestly one of my favorite games of all time.
Vision: Soft Reset – a metroidvania, but you can travel backwards and forwards in time and this really matters for gameplay.
Bombe – Minesweeper, but instead of solving the puzzles manually, you create rules (“if there is a cell with the number N and there are N empty cells around it, mark them all as mines”) which the game applies automatically.
SOLAS 128 – a puzzle game where you redirect signals in a huge machine, just a great experience if you like puzzle games.
