No worries, bugs happen, and it's still a standout for me either way! (I also did watch Kyle's stream so I got the full story!) I did give it another go just now and unfortunately the bug now happened on the first challenge and then again on the second challenge on a subsequent attempt. I go to set a base and it drops down and then from there can no longer set one. Just thought I'd give some more info. that might be useful if you do plan on continuing to update it!
I downloaded the new version and gave it another go and made it to the end just fine! Had a lot of fun! However, during the final judging session, my piece floated up into the sky and disappeared offscreen...I guess it was so good it ascended to the heavens lmao I consider this to be the perfect ending. Thank-you for fixing the bug and thank-you again to the whole team for making such a cool game!
