Not Bad at all
The game is fun, but i would recomend making the first lvl shorter and easier just so the player can get get some upgrades without having to start over. the sniper bonus round is really cool but its kinda shooting into the dark. If you could just see a little bit of what you are shooting at it would be a much better bonus round. i only got to level two because i was waiting for the level to load and wasnt paying attention when it finally did. By then i was overrun. Maybe add some continue or something like that. Not a bad game though.
