Thanks for playing twice! I wanted the fuse cutting to give you more control over the timing, but I probably need to make its purpose clearer. Really glad it felt polished!
You are welcome, great game! I just tried to drop them as deep as possible since that seemed to give better results. If it went deeper though, and I had blast an exact point slightly before the deepest I could go, I might cut it then, or I might just wait before dropping it.
