I like this game.
I think camera should more focus on where i'm going.
After first death restart, the length stops increasing.
The gun sprites rotate incorrectly when going horizontally, i think.
Enemies sometimes spawn with and gain absurd speed.
Enemy spawn is conconsistent; 1-2 enemies on screen followed by a sudden 20 speedy enemy spawn.
I think the enemies should spawn farther from the player.
AND/OR regen feels too slow with how randomly you can take damage.
