Easy
The turrets one hit practically everything.
Reviews for "Space Voyage - Invasion"
Nice game
Right now i am in level 23 and i have 100000 cash, i would really appreciate more upgrades, but its really nice game
Clicky bad
I've always wondered if games like his are made by companies that sell mice.
Regardless of that though, they cause a lot of wear on a user's hardware, as well as simply being a lazy game-play mechanic.
I would highly suggest adding a cooldown on the main gun, and allowing the user to hold the mouse button to keep firing instead of constant clicking.
Too easy
Make it more challenging. It was very simple to beat, but still a pretty fun game.
I dunno
Music got very annoying, gameplay was boring after a while.
Not bad but nothing great.
