Vega Magnitude
Description
Vega Magnitude is horizontally scrolling shoot'em up which has no goal except reaching a high-score. The game's speciality is that the ship has four weapons which are identical except for their colour - the catch is that standard enemies (which fly from right to left in a straight line and don't shoot) are only vulnerable to the weapon of the same colour. If the wrong weapon is used, the shot just reflects back and may destroy the player. The second enemy type are kamikaze pilots which are always perfectly aligned to the player's ship and can only be destroyed by activating the shield. Again, it has to have the right colour in order to count.
Additional things to look out for are bombs (can't be destroyed and eventually explode into coloured bullets which need to be avoided by dodging or activating the shield) and power-ups which have positive effects when collected, e.g. points, an extra live or a temporary special weapon which destroys everything. Each hit is deadly and the score multiplier gets higher the more right the ship is (which gives less reaction time).
