itch.io

I had the same trouble myself going to full-screen. I activated the full-screen button from itch.io to provide full-screen mode. Sometimes, the game loses focus after it loads. All you need to do is left-click inside the game window.

My current record without getting a crack is 15945 CM. It would be nice if there was some music to listen to while you climb.

Blessings are required to both stay at the level you are on if you fall off and to fire the Bible's beam at a demon currently on screen. I gave the hint about the Bible's beam in the updated description.

You can use the left, right, and up arrow keys to move the character. The only thing the up arrow key does is make your character jump. I cannot change anything until the judging period is over. It works for me in Chrome. The game page scrolls in Microsoft Edge until I press F7 to turn off caret browsing before I run the game. It now works in Microsoft Edge. Sometimes, the issue is a browser issue. Let me know if you still have trouble.

Updated: I have added a full-screen button as an option from itch.io. You can try that too.
