Also by double speak games, and open source gridland is a variant on the match 3 style. During the day phase, you accrue and store resources, and build stuff. During the night phase, you fight.
Open source idle game, but not quite. It eventually expands beyond watching numbers go up, into a sort of roguelike, where you can wander the world and collect stuff. And die. Die a lot.
A Dark Room was where I first saw the @ symbol used to represent the player character.
Think enter the gungeon combined with superhot, but simplified a lot. It’s a turn based bullet hell, and an excellent arcade game playable in the browser.
EDIT: I’d also like to take this oppurtunity to talk about flashpoint. Flashpoint is a massive archive of basically every flash game and animation, and you can even play them again.
However, in addition to flash projects, I also noticed that flashpoint also archives HTML/HTML5 games… but only a subset of them. Although flashpoint’s primary purpose still is as a flash archive, it can also be used as a curated list of HTML5 games.
