That's weird. If you bought the game on its own, not as part of a bundle, you should be able to claim a Steam key on that page.
Email me at contact@spacegoblingames.com using the same email address you used for the purchase and I'll hook you up.
When I first released Seedship in 2017, it was on philome.la, a free hosting site for Twine games. Later on I moved it to its current home on itch.io, and also made the Android and iOS apps, but a lot of old links to Seedship you can find online still point to the philome.la version.
philome.la was discontinued and became read-only in 2019, so that version of Seedship is still there, but I can no longer update it. This means it contains a few minor bugs that I've since fixed in the current version.
If you're playing Seedship online or sharing links to it, please play the version here on itch.io! (https://spacegoblingames.itch.io/seedship) And in particular, if you find a bug in the philome.la version, please make sure you can reproduce it on the itch.io version, because there's a good chance it's been fixed.
Please don't use Seedship (or any of my other games) as the basis for any genAI/LLM project.
Generative AI is massively damaging to the environment, is built on stolen work, and has been shown to damage its users' ability to think for themselves.
If you really want to create Seedship-based genAI text or artwork, I can't stop you, but please don't post it here.
Right at the top of the game page there should be a thing saying "You own this game" and a Download button underneath it.

Clicking on that should take you to a page where you can choose which version to download.
Do you not see the "You own this game" button, or does something go wrong when you click on it?
It looks like you're playing the version hosted on philome.la. That was the original site where Seedship was hosted, but the site was discontinued and became read-only in 2019, so I can no longer update the version of the game there and it's forever stuck on version 1.3.1.
I fixed this bug (and a few other minor bugs) in version 1.3.3, so the itch.io version and the mobile app versions don't contain it.
All I did today was label the file btcg_win.exe as a Windows executable in the itch.io back-end. I didn't make any changes to the files themselves, so I don't know why this would break something for you.
Do you want to try downloading the game from the website without using the itch app and see if that works?
Thanks for the offer, but I'm no longer developing the game and I'm happy with it in its current state. Also I deliberately made it simple because I thought that would be most artistically effective, so I think pixel art and features like ship building and ship upgrades would have muddied the premise.
If you want to play a larger, more complicated game with more scenarios where you can do things like upgrade your ship, you should check out this game's spiritual successor: https://johnayliff.itch.io/beyond-the-chiron-gate
Thanks for letting me know. I'll try to get this fixed this week. In the meantime, playing the web version in your phone browser is basically the same experience as playing the app version.
*So* annoying that older apps just stop working unless the developer rebuilds them for the latest Android versions.
1. Yes, the PC version is the same as the iOS version so should be equally blind accessible.
2. Unfortunately there's no way to sell an iOS app from itch.io or for itch.io to know that you've bought it from the App Store, so yes you'd have to buy it again.
3. There's no required typing. You can optionally rename your spaceship and explorers, and that involves typing in a new name, but if you choose not to do this then there's no typing.
