Very simple artstyle but conveys everything clearly.
The UI shop could definitely have a bit of delay before activating (or making you hold to buy an item) since I am usually spam clicking to shoot and then the ui just pops up and I accidentally buy something by accident without getting to read.
If the intention was to not have the player spam click and manage their shots it might have been better to make the clock longer and change primary fire to be more like the railgun so the player has to kite enemies into the right formation before shooting to hit multiple at once in order to properly gain time.
The enemy designs are simple but still manage to create meaningful variation in how they are approached which is cool :3
