There're yellow triangles on the walls in each room. Use these to open doors. In many cases you'll need to fire your laser in order to ricochet the beam off the walls and connect with the triangle, opening a door you wouldn't otherwise be able to open safely.

Basically, blow up everything in every room you enter. Press 'U' to use items in your inventory, bombs, stop time, barriers, or shields. Bombs of course can be used with 'button two' on the joystick. Stop time stops time. Barriers blow up things for you (make sure they don't backfire on you and kill you instead). Shields protect you from everything for a short period of time (The exception to this is the green cannons, your shield will disappear after being hit once by a cannon, so get rid of those green cannons right away).

In order to save people, first secure the room by blowing up everything and walking over those squares so they turn green. Then walk up the person and hit 'Enter' a few times to see if the person has anything to say. If not, just walk with the person (being very careful to keep the person from walking over electric shock pads) over to the red arrow in the room, and the person will walk out. At the end of the game the original author had saved approximately forty people, so you know you'll be doing fine if you average about four people on each level. Some people you attempt to save will turn into "fire guys". Blow them up with a bomb immediately. You can discern the real people from the fire dudes by firing bombs against the wall. If a person shakes, he's real. If a person stays stationary, he's fake and will decapitate you.

Those white open triangles are keyholes. You need to find the key on each level for each keyhole. Sometimes there may be as many as five keyholes/keys on a level. Just get the key and touch the keyhole and the door'll open.

Are those transporter things rad or what? Notice how you can shoot into them. This is valuable when you have to shoot a yellow triangle from a distance to make a door open. The bomb will enter the transporter and come out of the other transporter, connecting with the triangle perfectly (if you aim is correct).

In one room in the game you'll not be able to open one of the doors unless you blow up one of the yellow rods. It'll then unlock. You don't have to worry about that door anyway, since you've already been given the pass code/userid.

When you see a computer, walk up to it and you'll get some cool graphics and information about Genoq. Mostly they're not of much use, but two of the computers ask for pass codes that were mentioned above and are very important. In one room you'll walk to the computer and suddenly be transported to a weird area with a guy resembling the T-1000 coming after you. When this happens, restore the game and when you get back to that room, DON'T TOUCH THE COMPUTER AT ALL. You do not need to, and you will only lock yourself in the room by doing so.

It's believed that level 90 is the final level in the game, so even though it might look like you've reached the roof of the damn building, you haven't.

Level 90 (the last level) is the weirdest level of the game. You'll encounter Derrida (the guy you want to give the package to). Just talk with him and then touch him. Then walk to the right out of the weird screen.

Then continue walking diagonally right and down, then diagonally right and up to get out of the EYE screen. Then talk to the second Derrida and walk to the top of the cross and exit. Continue walking right out of the next room. When you see the glowing dude, wait until he starts walking then get the hell out of there to the left. Follow the red arrow path downward and walk to the keyhole at the bottom left of the screen. Touch the thing when the glowdude is about to walk in front of the radar dish, and he'll be fried and bloodily explode. Then walk out and back to the room in which you first met the glowing guy. Touch the computer for the fun of it and then touch the jetpack and fly away to victory.
