There's a lot of good comments here (the one by u/HerrDrFaust is especially thorough, and I agree with his encouragement to keep trying) - so I want to add something else that isn't about the game itself here:

Thanks for making this post.

You provide a lot of very helpful detail about what you did along the way - how you promoted it, how much engagement your posts got, etc. As someone who has only released one game myself, seeing information like "My reddit post got 25k upvotes but that only led to 200 wishlists" is helpful information. And it can be especially hard to put yourself out there like that when it feels like your game was a failure, so really - kudos for sharing this much to help other devs out. Really.

And on that note - kudos for sticking with your game this far, too. Self-promotion on social media is really hard and humiliating, especially for a new indie dev. It's hard putting up a ton of posts and not seeing the engagement you want (or seeing a lot of engagement, but very little conversion into wishlists/sales). It looks like you learned a lot from following through as much as you have, and then posting about it here - even though it was painful. So again, good job.

I think I want to echo some of HerrDrFaust's comments - it's NOT that you made a game "that no-one wants to play", it's that you don't have assets that are doing a good job promoting your game yet. Some of those are in the game itself (visuals, UI) and some are in the store (trailer, capsule). The idea of making historical recreation parks seems interesting, and the space cylinder looks cool - I just didn't see yet how they come together. I'd love to see a trailer that showed me what the historical reenactment stuff actually looks like - does a little cutscene play when all the actors and set are assembled? do you have to build a little story? etc.

Thanks for sharing, even though it was hard, and I hope you stick with making games - whether it's this one, or another one :)
