I really enjoyed the gameplay and the visuals!
I'm missing some visual feedback when using the thruster while airborne.
Although looks natural, some people might get lost on how to use Bombs and what which powerup does by looking just for the letter. Suggestion: some tutorial for commands and maybe using the target window to preview how the bullet will look like and it`s strength would be nice.
It's a super fun game and I could play through the whole quarantine.
