Space Shooter Infinite

This is a space shooter, game levels are generated randomly, this means that

every time the player starts a new game the level one will look like
different (both graphics and music). The game is infinite, there is no
ending, to beat each level the player will need to get to the end-level
boss and beat him, also the game features a in-game shop, killing the
opponents will make the points counter increase, at the end of the
level, the points will be converted into money allowing to purchase more
effective equipment like double fire, rotating blades, frag bombs,
missiles and shield with a timer. Equipments are expensive so the player
will need to kill a lot of enemies to raise enough money necessary to
purchase additional equipments that are quite expensive.
