Pretty cool idea. I initially was very frustrated as I attempted to speedrun the game. If this was the intention, I would recommend putting a health bar or just number of times you can get hit before you die. Once I started to play more tactically however, it was really quite chill and nice to play. Add some more interesting level designs and maybe some thing to make moving across the map more even more interesting and polish it a bit more and this could totally be something pretty cool.
