Another few features maybe worth considering.
*Making the charged shot faster and the red ballistics spreading quicker than the grey ballistics.
*Having the alternate left/right number counter on the hud.
Add a message exactly the same as "New High Chain!" but for every chain thats present. Be careful with powerups. It may detract from the gaming experience. If you do wish to add them on, please make it optional. I love this game very much, and it has alot of potential. Keep updating!!!
I expected a boring shoot em up with no real gaming experience however this game incorporates two great gimmicks for a nice gaming session. 5/5. Keep up the good work!
There's a rather large bug. Once you complete all challenges, there's a level called "undefined" and it becomes black with all values on the hud coming up as "undefined". It's probably caused by no data being present for that level but maybe put in a replay of all other levels instead.
The game is based on another long time running game called "Soldat". I do however admire the effort of placing it onto flash. If you're looking for a multiplayer version, Soldat should cater to your needs. I highly suggest you google search it.
