Neat game, some initial impressions i got while playing:
* Gameplay is based around keeping the correct distance from the enemies and strafe around them, the drop shadow from the weapon is a nice touch.
* Controls map poorly to trackpad
* Bit of an info dump in the beginning, which i skipped. Then i found that the recharge mechanic is not explained in the pause menu alongside the rest of the controls
* There is not indicator of enemies outside of you field of view, you have to actively look around
* I was confused why why i had to wait a little at the end of the early rounds as i hadn't noticed the timer, perhaps skip the remaining timer if all enemies have been killed? Add the remaining time to the score?
