Absolutely incredible arena wave shooter the more I got into it.
I would say the biggest detractor is how small projectiles are. I wish they were even just 1 pixel wider, although I understand that you were probably going for a highly specific strike zone.
I wish the relics could be moused over for descriptions in the pause menu.
I wish shields changed color depending on how many impacts they had taken. This wasn't clear, nor was it clear that recharging your shield as the police cruiser when you already have a shield up doesn't "supercharge" it or anything like that, so it's effectively wasted. I sorta wish it wouldn't let you reactivate the shield if you already have a fully charged one going, just to prevent player-vs.-UI mistakes.
Man, wave 14+ is suuuper-interesting, but that's where I picked up the relic Backshot that says "Fires behind you" but as the police cruiser, it ended up instead firing 3 shots still in front of me, but at a slower pace that expired closer to my ship than my default buckshot. Is the description misworded, or is it not supposed to do that?
I understand that the long time before waves is to allow the ability to cooldown to run its course, but it's kind of awkward. Why not just have the cooldown insta-reset instead and just summon the next wave, or at least make it somewhat faster?
Man, the boss at wave 21 is extremely unfair against the police cruiser because all of its shots are shield-piercing. What gives? There's no warning of such a massive debuff like that. Is this a bug?
Anyway, clearly I love it and want it to be even better. Great work!
