Alright, here's some free stuff that might work:
- Daybreak Empire - Strategy RPG. In development, demo released February 3, a handful of comments and a couple of videos. Ran without problems on my laptop.
- Signal - Point and click adventure/puzzle game. Made in 48 hours for Global Game Jam 2018. One comment about being stuck on a puzzle. Worked like a charm on the laptop.
- SUGAR! OVERKILL! - Run and gun action game. In development, demo released two days ago, has received three comments, one video. The game ran nicely on my not very new Windows laptop, only problem was that it wouldn't recognize my joypad.
- Fell Seal - Another strategy RPG. In development, demo released August 27 last year. Five community threads. The graphics were flickering a lot on my laptop, and this game also failed to recognize the joypad.
We can pick the topmost entry on this list that isn't vetoed by anyone, or do a straw poll among the participants. Either approach works for me.
