Hi THECHPOTLE, thanks for letting me know about this. It's fixed in v1.1.1 which I have just uploaded to Itch.
The cause of this is that School is Hell 2 is externally hosted, so it can't be played within Itch.io. The in-game link should now open in a new browser tab, where you can play School is Hell 2 (btw, it's VERY incomplete). Here's the link again:

NB: Philome.la, which hosts School is Hell 2, is available as a static version of the site only. You may want to download that game in case the owner ever decides to shut down the site entirely.
