The concept and art is great. Music and sfx suits the game very well. It looks very polished but I've problem playing on touchpad. Sometimes it cancels my movement and the number of steps are not accurate (idk why it probably adds number instead of reseting) but it seems only visually broken.
Since the enemies can only move one tile it's pretty easy to avoid getting hit but I assume it gets harder in later levels but for me the progression / difficulty scaling is too low.
Overall, your submission is very solid for 7 days, really looks great and polished and definitely could be build into something bigger and even better. Congratz!
