I'll preface this by saying I did not play for long. If anything in this comment feels invalid because of it, please disregard that. My reason for not playing for long is because everytime I moved the ship, my frames would drop to 10fps. I don't know what kind of heavy code is in the background of this space shooter, but the fact that I can't run a 2D space shooter on a laptop from 2016 is a bit concerning...
Now onto my main critique. The art style feels very unfinished. There's a lack of consistency between enemies, player, and background. There are no animations, the logo for the game feels like straight out of Microsoft WordArt, and there's a lack of main menu UI. Maybe you were dealt a bad hand with a lack of artists, I don't know, but this feels very unpolished.
The part of the game I could play felt a bit janky as well. My bullets felt like they had little to no impact with the enemy, and I very quickly had my health reduced to 10% with a faceful of 4-5 enemies that would not die.
