Really great use of the theme! Countdowns are central to the gameplay in an interesting way. It’s a space management game where you also have to consider time as a dimension (eg. not only where is this ship now, but where will it be when this bomb detonates in 10 seconds), which is super cool. Making the bombs unmoveable after being placed made it very deliberate.
The game got pretty overwhelming pretty quickly, though, which meant instead of strategising I mostly just panicked. There are way too many ships & bombs to play the game as intended, I think. Another issue is that ships can enter the screen out of nowhere, meaning even if you place a bomb in a 100% safe spot, a ship could just spawn there and kill you by no fault of your own. An indicator + timer of where ships will appear would be really helpful.
(By the way, just have to add somewhere - love the slide guitar in the soundtrack. Super summery.)
Great work overall!
