The “crash” is intentional. We were a bit tired at that point and didn’t have the ending implemented yet, so we made the game close itself when the player reaches a specific point. It’s not the most elegant solution, but it was the best we could come up with at the time.
The game was originally very different, but we got a bit too excited and had to cut many features. We may continue developing this idea in the future, as we really like the concept. Thanks for your feedback!
