Made it to Level 9; will need to go for higher score after trying out the other entries. Good controls, nice sound design and music (not too loud or grating also helps). Love how the lives system is visualized after you lose one. Also love the visual representation of the timer you made.
Good challenge and design for the most part, though the only gripe I have is with a few tile fill outs in regards to objects blocking your path. Sometimes when trying to get within a close enough range to fill in those tiles it won't register a fill in at certain points, whereas if you move to say the north portion of the tile with the same parameters it will then fill in.
Otherwise very solid and straightforward design.
