my computer won't let me open the file, because it doesn't recognise the app. It would be great if you could make a web version so that I can play it
Appreciate the interest, I wish I could get the web version working, but this is what's happening with it - working on it though! The download should be perfectly safe though, just a standard Unity game. I realized the zip accidentally contained a version of the web build with it, which I wouldn't think would matter that much, but I've re-uploaded it without that. Maybe it'll be less offensive to any anti-virus protections that way. :)
I originally had some anti-spam mechanics included, but I felt they just made the game less approachable for a gamejam setting. If I were to develop this further I think I would include something like that. There were some harder jumping challenges I had planned but didn't really get to implement, though as a theoretical first level of a game it's probably okay for it to be on the easy side!
