After having read that really detailed review down below, I don't know if I can add much as he/she says pretty much what I wanted to say.

What I will say is, I feel that in normal mode it takes too long to speed up and there aren't enough obstacles. I think there should be slightly more, even in the earlier stages. But that's just me & that's probably why crazy mode was released(?) I'm probably wrong about that.

Also, I don't know if anyone has pointed this out, but I did find a bug. A bug that only happened once, mind you. When I first played Normal Mode, I crashed into an obstacle and then my ship disappeared but the game still continued. I was still racking up points & the speed was still increasing.

Other than that, I think this is a cool game. I really enjoyed it & I'll keep an eye out for it seen as you'll be updating it!

You did some great work, 4/5.

nicely made, needs more projectiles imo

Cool idea, kind of simplistic at this stage. Hard to aim projectiles...retical needs to be more intuitive.

vector drive! sounds awesome, let's see if it IS AWESOME
PLEASE DON'T BE PRETENDING TO BE AWESOME PLEASE I'VE SEEN TOO MANY OF THOSE GAMES TODAY

menuscreen! it looks rather simple in a way which is neither a good or a bad thing
it bothers me a bit that you list the controls but the title is for the most part nowhere in sight
i think i'd prefer controls in a separate page
or perhaps visual controls ie. it shows the directional arrows and WASD as the buttons for movement etc
the buttons on the menuscreen don't really reflect the sort of basic glowy wireframe thing the game has going on, so changing them would make it more consistent
i did notice something about the controls which i will bring up in a bit

the typography... ehhhh, as i said, very simple
i'd like it to be a bit more 'digital' or futuristic because this is a pretty futuristic sort of game, but i don't mind it much
i think the colors might be a little too bright and the font size a little too small though

visually it's a neat little thing
it doesn't do too much or too little so it feels just right, at least to me
i'm curious about the christmas version though, haha
although i've gotta say stars aren't actually tiny dots in space so it's weird for them to go by like that
but it's also very... calming? to see them go by, along with the asteroids

the gameplay is incredibly simple, at least at first, but here comes what i said about the controls...
using shift as a control just isn't a good idea, but i'm not sure if you get to press it often enough to enable stickykeys accidentally
another thing i noticed is that the asteroids appear to just phase into existence close to our ship later on instead of gradually coming towards us, i don't know if that's intentional but it certainly looks weird

it's not a very exciting game but i found the combination of the game and the music to be incredibly calming and even fun later on
maybe some things other than Just Asteroids would be neat, i'd think that'd provide more of a challenge
and visually it'd be interesting if some planets or something would be visible in the distance
at least in vector mode, just to get some other colors in

idk if it'd still be a retro-like arcade game then though, haha

but i'm very impressed (10-20 hours! wow!) and i enjoy this game a whole lot, personally. it can be improved but i think it's fine as it is.

No score-keeping system at all yet? Are you kidding me? That should be one of the first things implemented before any sort of release... It also needs a score multiplier in-game. There's no cool power ups from what I can tell. Could use things like invincibility, and things like that. Got really boring after a while and the speed went up way too slowly it seemed.
