Hi!
The development console in production is cool! You can debug right away :D, it made me very happy).
The exit button for a browser game seems superfluous, but I understand that the game was developed on Unity, so for operating systems it is absolutely necessary an exit button, but for a browser game ..., I don't even know if there is such a possibility to programmatically close the browser tab :).
Regarding the game itself, I did not have enough information about the controls, it would be good to have such a tab with information as for me in the menu list.
I loved the Spacebar acceleration mechanic! But it seems that sometimes there is some kind of teleportation of me, maybe due to the fact that during acceleration I am left in place, or something else.
Shooting is extremely difficult), I understand that I can only shoot from one vertex of the triangle, while my opponents seem to shoot even homing bullets (green) :D.
Maybe if I added the acceleration of my bullets, since they seem to be slower than the opponents bullets, the odds would be evened out a bit. Or give the opportunity to shoot from each vertex of the triangle.
Because now I couldn't pass even the first level :), I guess that if I killed all the opponents, the door behind the red line would open and I would go further, but the game design turned out to be difficult for me
The map looks cool!
Overall a good game! Graphics of primitives is strong! I used this myself :). So how about me - balance the game's complexity a little, figure out the player's jerk/teleport, or if it's intended to be so, then describe it somewhere as a feature, add a controls guide and you can play!
Good luck!
P.S.
I saw your description under the game and using the time stop I was able to pass the first level! But it's still challenging, but also fun).
