Simple concept with the potential to be very interesting, but some bugs prevented me from fully enjoying the game.
I feel like HP going down is not the most creative use of the theme (especially since there does not appear to be any UI for the health points remaining?), but the actual game was pretty neat. It felt like playing a chess endgame and messing with tempo to make sure I was stepping on enemies rather than the other way around. It took me a while to realize my goal was to step on the enemies that were killing me on contact rather than just trying to evade them for long enough.
If health was supposed to be moves remaining, I feel like that should have been communicated more clearly. It was not clear why I did not immediately lose after getting hit by an enemy nor how I was supposed to be able to restore moves.
Bugs: The health tracking felt inconsistent and there were many instances where stepping on enemies simply did not work or I lost the game immediately. Sometimes it was not clear why I lost.
I know my feedback is mostly negative here but I do see the beginning of a pretty interesting game here. Besides fixing the critical issues, better UX would go a long way, as well as tightened design to help the player focus on the strategy and perhaps limiting the number of dashes in some way. You will only improve from here!
