Thanks for checking Strelly! Hopefully we'll have a better working web version in the future but for now we do suggest focusing on the downloaded version over the Web one.
Thanks for letting us know! It's likely the web version that you're playing as that isn't tested and mentioned in the description. I do suggest downloading the desktop version to try again!
Dang, we didn't run into that when we were testing, so it's probably something we missed. Sorry about that again, we do appreciate you guys trying the game out!
