Thank you for playing my game and for your feed back. Part of how I was trying to fit the bullet hell genre with the game Sonar Sight came out to be was forcing the player to choose to either move and risk running into a mine or stay put and run the risk of being hit by a torpedo they didn't detect, and because of that there aren't really any safe zones on the map. However because I ran out of time you can 100% just drive off the tile map and sit in null space safely if you go far enough.
Another note I just realized you made a game called bugs and your profile picture is a frog, I find this pretty funny :D
