I've fully upgraded the laser and grabbed as many orange upgrade tokens during a level (voice says, weapon maxed), and overall my main weapon feels overwhelmingly underpowered...any plans to modify it? Thanks. Also my shields are two away from max and I'm worried it may be the same for that as well... edit- yep, they feel very underpowered as well, especially for being fully maxed....

Can the game be played using the mouse for movement and mouse buttons for firing weapons?
