139.4 sec / 34 deaths.
This is one of those "simple concept - fun game". I didn't like the collision detection, one one of the levels, I wanted to jump right between the floor and ceiling and I could do it very rarely. So sometimes I stuck. Also it would have been good to make the laser cannons some different tiles, but it's actually not a big issue, after a little observation, it was clear where they're coming from. I enjoyed the game in overall, the pacing was good, the levels are small enough to try over again and again and again after many deaths without any frustration. Maybe a smaller collision box to the player would have helped to avoid those questionable sticking, and not able to fall down or jump between things.
The game kinda reminds me of that level from Megaman. (Don't remember which stage though, but has similar lasers and had to go down quickly.)
