I think it took 30-40 minutes or so? Once I got established in my strategy I was zooming through rounds.
As far as suggestions, I dont really know. You have a unique fusion of genres here, deck builder and incremental game. People are recommending Balatro, but Balatro's more of a rougelike than an incremental, where you try to make the most out of the cards you get in a run and try to build around it. Rougelikes tend to have alot of build diversity, with many different options that can work well given the right circumstances and deck. They're also run-based, where (almost) all of your progress is wiped clean each playthrough.
With incremental games, there usually arent ways you can lose, not doing well just makes it take longer to get to the next unlock. Your progress starts slow, then builds up to that satisfying 'number go up' feeling. Most incrementals have points where your progress starts to plateau and it slows down to a crawl, and at that point another 'layer' gets introduced, adding more mechanics that, again, start slow and build up to even more number go up. A prime example I can think of as a pure incremental game is Antimatter Dimensions. The numbers in that game go absurdly high, and there are multiple different layers of progression which add new mechanics. And each layer incentivizes you to shift your strategy accordingly to help push you past the plateaus. Also, incremental games tend to let players leave and come back, with some sort of offline progress.
With your game, I'm not really sure. There's many avenues you can take here if you plan to keep developing this. You could lean into a more Balatro type game, and make a bunch of different kinds of rocks papers and scissors that have different synergies and a more exponential difficulty that you'll need a strong build to overcome, sort of expecting players to fail at a certain point. You could lean more towards an incremental, and introduce new mechanics once you earn enough money and your progress slows down. Hell, you could even make it a multiplayer game, where you alternate between playing like the current gameplay and matchmaking someone who's at the same-ish progress as you. Sort of like a Super Auto Pets or like Teamfight Tactics or something but with rock paper scissors. Just some ideas, as the current game you have feels like its not quite committed to any one direction past the core loop.
Again, I do think its pretty cool, and I wish you luck with whatever you decide to do :)
