The look and feel of the game and gameplay is really clean and solid!
One thing I wish there was was more motivation/reward for the player. E.g. after playing once the only motivation I have to play more is to beat my previous self or other players, so something like a leaderboard at the end of rounds that would allow me to see how I did this round vs the last rounds would be fun! I was actually hoping other people might be posting their scores in the comments so I would have an idea of a good "score to beat" to get a lil more fun out of it.
A real shooter style minimap would've added just a little bit more fancy touch as well.
