Hmm. A promising start, but it was too frustrating for me to play for more than a few minutes.
- It doesn't give enough time to react before something kills you: you should have more than a fraction of a second to evaluate the situation after starting the game or spawning a new wave of enemies before you're dead. Similarly, ONE-SODA tells you which way it's going but then just barely gives you time to get out of the way.
- There's no audio feedback when you hit an enemy. The knockback alone isn't enough for me: I'd like to see a sound effect and maybe a white flash or something. Most limited-bullet games (the classic Asteroids, for instance) just don't let you shoot again when you run out of bullets. So they reward accuracy (if you miss, you're defenseless until your bullet dies). Your game is more friendly in that sense, but if you fire again before you hit the enemy, then nothing happens. So in the heat of the moment, it's hard to tell if you're hitting the enemy a lot of times or just firing at the air in front of them a lot. If there is only one sound, I'd prefer it to mean "you hit an enemy!" (which I'm often not sure of) instead of "you fired a shot!" (I know that. I just hit the button).
- It's hard to tell where the hit-boxes are. Sometimes I got killed instantly, and sometimes I thought I should totally have died but I didn't. Particularly with ONE-SODA after the first three enemies: I couldn't tell if it was invulnerable a lot of the time or if I just wasn't shooting it in the right place.
- It seemed like the enemies switched on a timer? Sometimes I'd kill one and then just be standing around with nothing to do for several seconds before another one activated, which was boring.
But I like the idea and with just a little more polish it could be a lot of fun.
