Great game.
this is a great game. Very addicting.
I've recently been playing many old-school shoot 'em ups and this is a worthy tribute to them. Sure, the slow down could be something to complain about, but I use them to my advantage as well as others experienced in this genre. In my opinion, this game is a little too easy. The normal difficulty level is what I would expect a easy difficulty level to be. That bring me suggustions for the next installment.
-either make the other two weapons more powerful or weaken the purple weapon in one way or another (like making it hard to get).
-more power-ups are nice, but not a necessity.
-make a sadistic difficulty setting where a average enemy shoots many bullets in a rapid rate, explode in damaging debree, and when you die you return to a checkpoint. It'd be a cool setting for the hardcore players, but I understand it could cause some problems in more ways than one.
That's all I can think of.
First time score in normal difficulty: 4638000
Time for me to try out the hard mode.
