I really like the graphics, the screen shake reminds me of Nuclear throne. The game could definitely use some music and sound effects (apologies if I missed them)

Aside from that, it feels the game difficulty isnt increasing, I was able to stand in place and continue shooting, with the only trouble being running out of ammo and having to wait on reload. Would be cool if there were some ground obstacles so the player would have to continously move, alongside enemies that shoot projectiles.
