Thank you for your feedback! I'm glad you enjoyed the game for the most part! I wanted the player to feel like they were floating through space with the velocity mechanic, while also being able to let them stop and move slower to avoid leaving the signal zone and dodge bullets better.
The reason why I was thinking of having destroyable projectiles was because I didn't want the player to be able to spam-click enemies without consequence, but I can see how it makes the game way more difficult. There are probably other ways I can do this better in the future (like making a heat/cooldown mechanic). Also, I agree that making a minimap or some other navigational system would help gameplay. I would've wanted to do something like that, but I ran out of time.
Anyway, thank you again for playing my game, and I hope you enjoy the rest of the jam!
