Ultra Asteroid Defence DEMO02

I really dont get the point of submitting a demo like this, way buggy and what not, does show some promise when its finished though

i can't even shoot... 1/5

Missiles seem entirely pointless. Moreover, the strenght on the missles can be increased beyond 3 (at four it still works, at 5 and beyond it doesn't fire). The energy for the shots can be increased beyond the stated maximum. Advancing the power of the shots beyond 6 is pointless, as at 6 only one enemy requires more than 1 hit, and that enemy still takes 2 hits with level 8 shots.
The scoring system is unique in that the penalty for random firing affects the total score, not a score for the level, which seems good in that it discourages simply holding down the space bar but strikes me as being the product of laziness. As was also pointed out, the percentage sign is missing from the accuracy penalty screen, which has doubtlessly confused a select number of people, and irritated quite a few more (7500 * 95 does not equal 7125. 7500 * .95 (or 95%) does).
Understandibly, it is a demo, but given that it is posted on the site, it doesn't deserve more than 1 star.

For some reason I was able to go past the 5th level... (the demo says it's a 5 levels demo).
To all who find this game too hard, I suggest pumping up laser power only. If you are able to get past the third and fourth level (the hardest ones on my opinion) you will be able to see laser levvel 8... big glowing ball of mass destruction :)

I kinda like it, I don't know why. I recommend multiple directions of attack and maybe an object that is being defended. Music Choice? Powerups?
