This is awesome. I notice you changed something that I now recognize was probably a bug. In the original, one could grab a credit and then Undo the action, keeping the credits but not wasting the movement squares. Here, the Undo also undoes the credit collection.
Hi! Thanks for the kind words. It's indeed a bug that you could Undo and keep the credits you collected, so this remake prevents that behavior. I also fixed a bug where you could use Bit-Man to "zero" your own programs, preventing them from being attacked.
