Yes, this happens when you try to loop at the edges of the map. Sadly we couldn’t fix it in time, and the enemies we couldn’t upload in time. Thank you for sharing :)
We used Python with PyGame. Like ohadish said, to make a runnable Mac build, I have to sign the build, which from my understanding requires a developer account for $99/year. Sadly, I’m not aware of a way to run Python on the browser either. However, the game’s page does contain the GitHub repository, with instructions on how to run the game in the README file, so you can do that if you want.
