-Playing on controller. I find it weird that you say ENTER/START for game begin, but only say "R" for restart, it should also say SELECT.
-Cute pixel art.
-Having bullet shoot rate tied to the amount on screen feels crap for a bullet hell, this isn't like NES Metroid where the range is so short to compensate when missing.
- Got to the gyroid, this pattern is way more annoying than the other boss. Also, getting damaged from touching boss feels a little annoying, but probably necessary to avoid easy safe spots.
-Took me several attempts to realize that TIME LEFT was actually for your death, not the boss. This is extra confusing since I've played games like Touhou where you can wait out phases. I don't know if you really need to explain it before hand, but maybe make it more obvious when you die to it, like making it flash red when emptied.
-Hold up, I just realized that my time goes down when hit. It isn't so obvious since the time is always changing anyway, and you're looking at where the action is around your character, it's easy not to notice the time getting cut when you're hit.
-Gyroid bullet 'pattern' makes me mad, mostly because I need to do the boring pumpkin boss again each time. I find the randomness and the arcs make it annoying to adapt to. Also, killing the orbiting circle feels pointless, it takes almost as long to kill it as the boss outright, and all it does it make the pumpkin shots a little more energetic.
-Skull dude is a fairly fun bullet pattern setup, died though.
-Seems like I actually carry some extra time between fights depending on how well I did, this was counter to my assumption of being reset, which I thought would let me be a little reckless on earlier fights towards the end. Getting hit once in pumpkin gave me 2 seconds, but a no hit gave me 10+.
-Finally found the 'focus' button, now I can get higher DPS if I get close to enemies. Or at least I think so, the limit based on bullets on screen makes it hard to tell if doing it from a distance is higher DPS since it becomes spotty in fire rate.
-I learn that low time also effects your next battle. This feels mean, a player sucking doesn't even get the baseline of 60s to beat the next boss.
-'Damage' of bullets seem random? Unless I read it wrong, the blue shots of Gyroid deal 20 seconds of damage, then another time it was like 2 seconds? I really don't get it. ([later..] Actually I guess it's just me getting confused from invul frames after getting hit?)
-Got to skele man again but died after the same amount of damage dealt to him as last time, I do not feel convicted enough to grind the previous fights to beat him.
Short and sweet I guess, if you expand upon it at all please add a continue system, or at least a practice mode.
