Pixel Orbit

i like this game a lot, i like it even more because the cover looks vaguely familiar to something that i'll never see in my entire life.

Yo, quick question...is there some way to reset my progress back to 0, so I can work out a speedrun of this? Or..y'know, play it from scratch, in general? I boot it up now, and I'm looking a full menu of bought items, and dunno how to clear that out and play from the beginning again.

Main thing I'll say is that often your choices for upgrades are significantly impacted by needing to fully max one out before the next ones are unlocked, and not having any visibility for adjacent upgrades gives you cases like needing to spend $75 on autoturret fire rate before you are able to buy or even know about its damage upgrade. While you can somewhat subvert this by temporarily selling things to buy into a specific tree, this is tedious to do and shouldn't be expected of a player. I'd say a simple solution would just be making the unlock requirement be one level in the previous upgrade instead of all of them.
Aside from that, projectile collision acts very weirdly - if two enemies are overlapping, one projectile can hit both enemies for its full damage. Equally, if multiple shots simultaneously hit an enemy they all disappear, even if theoretically the damage of just one of them should be enough to kill. This overall makes the multishot upgrade way less valuable as most of the time (particularly early on) you have enough damage to one shot enemies.
Lastly, as has been mentioned by other comments, the upgrade that automates your turret is very dissatisfying for two reasons:
1) It's boring. It suddenly turns the game fully idle in terms of just waiting 2+ minutes for each run to pass. While you do get the nuke a bit later on, there is far less thought involved in that than the main gun, which means in lieu of any other relevant features you're left with almost nothing to do.
2) In terms of strength, it's a downgrade. It's worse at aiming than the player is, and thus it's trading the convenience of not having to bother with the easy sections, with being less effective at clearing hordes or prioritising targets properly.
My main suggestion to fix this would just be to have some keyboard key set as a 'turret override' which returns manual aiming and firing (with holding left click allowing autofire).

In terms of ideas that I'd be interested which aren't explicit flaws, I think there is some missed opportunity with explicitly relegating the lasers and rockets to autoturrets - these seem like they'd be more fun and expressive to control with how the targetting and timing matters a lot more than it does for the bullets, maybe there could be some feature introduced that lets you swap weapons between the autoturrets and main turret to try and make better use of them.
In terms of enemies, I think it's currently severely lacking in variety, where each zone is just giant swarms of <basic enemy> and <basic enemy with somewhat more hp>. It'd be more interesting if you had things like fast enemies, or highly tanky enemies that show up in far lower quantities.

P.S. I find it funny how 'OPTIONS' brings up a menu where you have to click 'OPTIONS' again to actually go to the options menu. also what does LOOP do I couldn't tell.

"main turret regain control" <- such a terrible experience-ruining upgrade.

do the upgrades get better? 10% increase feels so underwhelming

$5 seems like a good deal for a laser turret, could I buy one at my local supermarket?

Amazing game!
But the disappointment that i cant make everything go at the speed of light is immense.
Chain lighting was fun tho
(Also i accidentally played signed out so rip my save)

i feel like each "enemy tier" should give more money because constant $1 per kill seems like not very much

Game is underrated (currently 3.2, should at least be upper 3s), even if not quite as polished as some other node-likes. That said, the main thing that felt bad to me was having to start from the beginning and play the boring part of the battle each time, even when leveled up and difficulty was trivial. Could use some sort of accelerate/checkpoint system to keep the time of each run down. I don't want to be doing 5 minute runes in a game like this, or even 2 minute runs if they all play almost identically. Still, a soild start.
