I have 4 games on Steam, and "review to sale number" ratio is all over the place, so it isn't that easy to use for estimation. You can get some idea, but 2500 is nowhere close really.
> Did you sell a lot more on Switch or something? I really would be surprised if an ASCII game could sell 20k on Switch.
About 2/3 of the sales were on Switch. I was surprised as well. I meant the game to be Steam-only, and then some of the players asked for a Switch version. I was blown away after the first month of release.
IMHO, turn based (or just slow paced) puzzle games are awesome for Switch because of the portability. In the evening when the kids have finished playing their Zeldas and Dragon Quests, you can lay back and solve a couple of puzzles until it's time to sleep. Looking at my personal play times, the game I play on Switch the most is "Baba is You".
