It is well made, but it lacks of objectives.
but it could be level based and with bosses now and then, like most of these type of games do.
And another thing, moving left and right and shooting rapidly makes the game very easy and
at some point boring and taking the fact that it goes on for infinity.
But in overall good game for a short period of time.
with god mode, it feels like a broken game.
it's pretty good if this is your first, but it still needs work. :/
