Level 0: Simply jump into the spikes at the right hand side of the screen.
Level 1: Step on the switch to release the blocks, push one onto the switch and jump into the spikes on the right.
Level 2: Push the block as far left as you can, then trigger the switch.
Level 3: Push the block on the floor underneath the other block, and trigger the switch so that the other block lands on top of it. Now just push the lower block and let the top block crush you.
Level 4: Simply hit the blue switch.
Level 5: Fall down the second drop. Push the block out of the way, then push it back so it's against the left side wall. Push the block at the top left onto the red switch. Now head back to the left and push this block into the first drop. This completes the circuit. Hit the yellow switch to activate it. To finish, make contact with one of the blocks in the circuit.
Level 6: Get the gun, and shoot the block from the right so that it falls to the ground while moving left. You need to crush yourself with this block.
Level 7: Get the gun, and shoot the bottom right most purple wedge. Run back to the red switch and trigger it. Once the bullet has passed the disappearing blocks, jump back into the bullet's path.
Level 8: Get the gun. From the top left, shoot the block onto the disappearing block, then stand on the switch. From here, jump and shoot the purple wedge (make sure to land on the switch so that the bullet isn't blocked) and run underneath the falling block.
Level 9: Get the gun. Shoot the block onto the switch and jump to the right before your footing disappears. Walk into the spikes.
Level 10: Get the gun. There's a gap to the right that goes into another room. Push the block into this room until it's underneath the other pushable block. Now shoot the green blocks to make them disappear so that the block falls on top of the other one. Push the lower block and let the top block crush you.
Level 11: Jump up to the top left, and then jump right onto the blocks at the top of the screen. Walk over to the spikes.
Level 12: Press "K" on your keyboard.
Level 13: Get the gun. Shoot the purple block and kill yourself on the ricocheting bullet.
Level 14: When the level starts, quickly walk right so that the falling block crushes you.
Level 15: This level wraps around horizontally. When the level starts, quickly walk left off the screen so that the falling block crushes you.
Level 16: The block in this level is a red herring - the level wraps horizontally like the last one. Jump to the left from the platforms into the spikes.
Level 17: Jump over to the block without triggering any of the switches. When you get there, push the block right onto a switch and jump off the bottom of the screen.
Level 18: There are invisible platforms to the right. Go for the spikes at the top right hand side of the screen.
Level 19: Push the block onto the switch, then have your shadow push the top block onto the bottom one. Now push the bottom block so that the top one crushes you.
Level 20: Hit the blue switch!
Level 21: Your controls are reversed. Jump into the spikes.
Level 22: Wait for 60 seconds and something will be along to crush your shortly.
Level 23: First, push the red circular switch closest to you. Now jump up to the top of the screen and push this block over to the right close to (but not on) the other circular switch. Using this block, jump back over the top to the left, and push the block on the left to the ground below against the right hand wall. Now push the other block on the ground onto the square switch. Jump up the right, and push the block from earlier onto the switch. Then simply jump into the spikes.
Level 24: Push the first block onto the switch. Push the next block to the left so that it intersects the disappearing wall, then push the right most block onto the switch. Get the gun and jump over to the left to shoot the green wall and push the block on the square switch. You can push the block through the wall if you've placed it right, and then get down to the spikes.
Alternatively: Push the first block onto the switch. Push the next block to the left as far as you can, the push the far right block over to the left onto the edge of the other block. You can then crush yourself by pushing the second block to the right.
Level 25: Collect the wings, and tap x to fly! Simply land on the spikes as soon as you get to them (if you get to the far right, the screen is filled with a ^_^ emoticon).
Phase 1: Walk over to the boss and let it crush you.
Phase 2: There is an invisible block to the far right. Jump into the boss from here.
Phase 3: Get the gun, and shoot the boss down by shooting the wedges. You need the boss to land on you for him to crush you (otherwise you'll need to restart).
Phase 4: You control the boss. Jump on your avatar!
Final Level: Just jump to the right and into the spikes.
