Hey can you contact me somehow? I'm dumb and didn't read and I underpaid for the Android version, then tried to just add 5 to my purchase, now I've paid 15 but can't download the Android version
I'm sorry to hear about the mix-up. Contact itch.io support to solve this.
I suggest you contact itch.io support via their support page: /support only they can help you with this matter.
Don't forget to mention your purchase ID and explain what happened just like you did here.
