Overall a fun game, top down shooters are an easy way to win over my heart and you did lol :)
Personally I didn’t love the ammo mechanic, i could be wrong but it seemed like more didn’t spawn in, so you had a finite amount to manage from the start without having any idea how long you’re doing that for. I don’t think the idea of having to continually move around for some reason is a bad one by any means, though, nor is requiring players to aim well. I just think it could’ve been done with positive incentives (get this powerup to make your bullets do more damage for x shots) vs negative incentives (get this pickup or else you can’t shoot). I think that would make it feel fun and elective, I want to get the thing cause it makes me stronger, while right now it was more like a chore, I have to get this thing to keep playing. Mechanically balance wise it could effectively end up being the same game. Of course, it’s all just a matter of taste!
Obviously more abilities, guns, enemies, etc. could make it better, but it was solid enough, played smooth, decent audio. I liked the particles though wish they had been recolored to match the enemies. I also found it wouldn’t shoot consistently but i’m like 95% sure it’s cause of using a trackpad. I’ll play a round on my desktop in a few minutes to make sure that’s the case (edit: indeed it was just my trackpad’s fault). It’s a really solid entry over all, congrats!
