Really cool concept, I'm a big fan of how you've tied in the timer and combat together and I love the use of emoji art. Some small things that id change would be that when you die/lose it felt like there was some kind of delay until the level restarted, this can feel annoying also the movement can sometimes feel a tad clunky particularly getting stuck on walls. Also some particle effects, screenshake, sfx always make this kind of game just feel better. Overall great job, love the concept!
