A game designer making strategy/narrative/puzzle games, anything that makes you solve problems by thinking and planning.
A few great ones that I can recommend are:
Best deckbuilder: https://lazyanttu.itch.io/wireburn
Best card game: https://lazyanttu.itch.io/the-weight-of-choice
Best RTS: https://lazyanttu.itch.io/battle-of-madonna-dellolmo
Best turn-based strategy: https://lazyanttu.itch.io/rouse-the-red-flags
Best complex grand strategy: https://lazyanttu.itch.io/the-maiming-of-time
Best mystery: https://lazyanttu.itch.io/threat-the-unknown-enemy
All were originally made as jam games and later polished more.
