Clever idea! I liked the concept of acting as a bug-tester for a game, and the form at the end was pretty cool. Really could've used a restart button (and a close game button). Knowing the concept from the get-go would have been nice as well as being able to test all the aspects before the form came up. For example, if both left wall is missing and the holes kill you, I couldn't test both of them since the game ended on death. Maybe use a countdown timer instead? The concept has a lot of potential, good luck with it (if you keep working on it)!
