Mob Factory -- Fun demo, tower defense crafting game. Zones don't get progressively harder, so once you have something successful you can just let it run for resources from the mobs and move onto a new area or add more mob spawners to increase loot
Viewfinder -- Short demo, great concept, can't wait to see more
Station to Station -- Cute puzzle game. Not a sim/transit game, trains are just the theme for the puzzle. Very pretty looking though
Laysara: Summit Kingdom -- City builder on a mountain, with different elevations and castes of workers (including yaks). Didn't get a great grasp on how much space management and avalanche control would affect the game.
Gord -- Grimdark survival city builder. Seems fun, has a story and will reset your town but keep the people as you move through the dark forest.
Thronefall -- More tower defense. Run around and shoot/kite as the king to keep enemy mobs busy. Balance more towers/soldiers vs economy. Extra modifiers for more challenge. Fun time killer, not sure how much I'd actually play it personally. Can only build in predefined spots, can't choose what goes where.
Wizard with a Gun -- Survival Crafting Roguelite with ~~guns~~ ~~spells~~ spellguns. Scanning enemies with the book while they're running around is annoying, but otherwise this was pretty fun. Supposed to have coop multiplayer, so I'd play it with friends once it's out
The elementary school thing you mentioned is definitely still a problem though. The schools are absolutely massive and you need a ridiculous amount if then to have enough coverage in your city, otherwise it's pretty nice, once they fix some more of the performance issues
