Although this game is great, i did have a couple of problems.
1. some of the cost balancing is strange. for example, 77 and 79 do the exact same thing except 77 is strictly better (immune) and 41 might be slightly strong. never found a good way to use 67.
2. i only played on the easier difficulty, so this next section applies to that - 53 is absurdly difficult, it took me a good 40 tries due to the fact that the opponent starts with 12 while you start with one - maybe make them start with 8 instead? alongside this, 97 and 100 were a smidge too easy for the finale.
3. The tournament is supposed to be the mode you play once done, correct? if so, it should definitely have more than one board. even though that is quite nicely balanced, having more board variety in the tournament would go a long way.
Thanks for the feedback! I've released a new update.
1. I swapped the numbers of 41 and 61, so covering stones is more expensive.
2. I re-balanced the fights for 53, 97, and 100. The last fights are the hardest for me to balance, so let me know if they still feel off. (Hopefully nerfing 41 made them harder.)
3. I'm planning to add a new post-game tournament eventually, with more variety and difficulty. For now, the intended post-game is to collect all 30 stones. Or start a new file and reach the tournament in 20 battles or less (excluding puzzle battles).
