Hi Hodop,
I challenge you to choose any level I made.
I believe you mentioned a preference for "short games", not sure if that means games that don't get you stuck in a stalemate or games that don't get too high a turn count. None of my levels have become a stalemate from my own personal playtesting, but some have had players exceed 60 turns to clear (I personally define anything requiring past 60 turns a long game).
These levels are recommended based on clear rate, although I leave it to your personal preference. Some of the levels I designed, I ended up being surprised how hard they were based on the actual clear rate.

Despite being a long game turn count wise, I think you will find the scenario an interesting "learning" experience from your original request
Clash of Titans:

This level is the hardest of the bunch recommended. This challenge was originally inspired from the Ceasar's challenge, so if you were able to beat that challenge, while this will be harder, it is beatable
Once again, the decision is yours to decide, and if you want hints on whatever level(s) you do choose, happy to discuss/brainstorm strategy and approach (or review your gameplay video to point out what you could have done differently)
