Love the design! You use the mechanics in really fun ways, and I absolutely love how crossing your path causes the fuse to split! It really adds a lot of thoughtful puzzle design. Overall, the puzzles were fun, although I think some felt a bit long or tedious where I would have to wait for the fuse to reach my placed bomb before continuing. Maybe you could speed up the base speed of the fuse and then increase it's speed slower to balance that? Or those long stretches of rooms could be sized down a bit to reduce the wait time. The "finish level" mechanic was interesting! I think it's a fun way to end the level, although I can see how it could become frustrating after finishing a tough puzzle, then messing up when trying to fit inside the purple/pink zone.
There was a small audio bug where I had completed a level and moved onto the next, but the bombs and explosion SFX were still going off from the previous level.
Otherwise, really polished game and great mechanics used in very fun ways!
