Game Review Time

What I liked

The premise was solid, with a respectable link to the theme, as is on a large scale. The controls are good, with a clear give and take on building the guns on earth as it rotates. The graphics were good, readable, and represented things which the narrative you were trying to present.

What I didn't like

I will say that you did a good job on adding sound effects to your game, a lot of games in jams skip that and suffer for it. I would however say that the sound effects are a little loud and intrusive. I would maybe tone them down a little, and add a small amount of pitch variance to them with each shot. I managed to win the game, but I still don't know how much a single turret costs.

Potential Improvements

Guns should probably have a bit of a hit box which stop other guns from being placed to occupy the same space, otherwise the best start is to build guns just at the very center of the planet, as that point rotates much faster than the outer rim, and thus covers more effective range. A bit of feedback when the planet is hit, such as a tiny amount of screen shake would be good. I would maybe recommend a bit of gun variance, with some firing out a laser, or a scatter shot. That is if you were planning to increase the scope of the game.

Overall Thoughts

The game was quite short, but sweet, with a tight game play loop that could easily be expanded into a good variety of options / directions. You have a solid base to build something quite interesting with an idea that has seen good execution.
