@polypickle Happy to hear that you like the music and my retro aesthetic. Not surprised to hear that you thought the main gameplay loop was boring but good golly miss molly did you ever crack me right open with your nerd stuff. I can't tell you how much I love seeing somebody dig into my stuff this thank you so much.
Now to respond to your nerd stuff 1. I seeing you explain it I can see how meditate is overpowered. Ironically you actually found the secret to breaking meditate I hoped most people would only kind of catch onto which is that it heals you for a quarter of the current value of your health so it becomes less useful the in health you become. I had hopped this would make people feel a little excited as there help dropped lower but I see you realized how to break it so congratulations to you.
2. You are 100% right about defend being a useless move. For reference when you defend it simply raises your defense stat in the game reducing damage (so if used with a boost it will prevent all damage from some enemy). There is a chance you did not see this effect as different spirits actually have different stats so some are better at defending then others while some have a higher base attack. On the note of having a 3/4th chance to add one to your enemys time. You actually are not quite right on this minor thing. Each enemy has a set of moves it picks from with some having favorites (for example some enemy's only have a 1/10 chance of meditating but have a something like a 6/10 chance of attacking).
3. Ding Ding Ding you hit the nail on the head. This was the exact strategy I used during development to speed through my test playthroughs as I was checking for glitches. I had hoped it wouldn't be so transparent but its good to see people figuring out the optimization like this. You are correct boost does stack logorithmicly (the exact formula is something like damage done = attack * boost where boost is stacked by how many times you press it before you attack) although there should be a limit to it which is actually 3 so you once again hit the exact right number so hats off to you.
I am really happy to see someone dig into this game like this thank you very much for this comment it truly has made my night. Many thanks to you and hats off to having such a big brain that you solved my game.
