I would really like to be able to reset the stage immediately with R key even when it goes wrong... (as of now you have to wait until it tells you "siege failed" and only after that you can reset it)
Otherwise a pretty decent game, save for few problems. First of all the beginning is quite frustrating, when you try to hit the enemy ships without any multiple bullet weapons. Second is the recycling idea, why not make it give a better item the more multipliers you have? Tired of using it to see that i got another standard weapon/shield. And third, it get pretty boring after a while, nothing really changes.
