Hi Csiret,
Thank you so much for reporting this! The kissing + inventory issue is something we haven't heard about before, and we'll do out best to patch it in the future. It should be possible to keep playing after restarting the game however?
Anyway, thank you for your patience - we're a super tiny team, and we're doing our best to resolve any issues when we are able. If you have any further issues, feel free to join us on Discord and we'll try to sort things out for you: valiant.se/discord
Btw your English is great, don't worry about it! :)
