Thank you so much for your feedback! I am so happy you enjoyed the humor (it's usually the focus of all my games haha).
From here on I'll address the bugs you mentioned, which DOES contain spoilers.
{SPOILER} Yeah, not allowing 2->4 was an oversight on my part. The kind of oversight that comes with designing a stupidly complex little puzzle game in 48 hours haha. Also yes, that laser bug is also a very good spot, so I'll fix that for my post-jam fix. It also sounds like you found my *game breaking* ending bug. I was devestated to realise after the deadline that one of the ways to reach the ending has a critical bug (I adress it in the description of the actual game page).
