I made Tiny knights commander for a game jam and it turned out nice. I got 50 out of ~700 entries :))
It has a web build, try it here - https://optimus-beg.itch.io/tiny-knights-commander
I just released an update with a second level, building towers, new enemies and game mode
It may be a little weirdly balanced since I was the only person balancing it, but it should be fun and not too difficult if you played any RTS before
Good luck Commander!
