Blinx: The Time Sweeper Cheats

Get easy money:
Choose to fight the Boss of Hourglass Caves. The Boss of Hourglass Caves  is easy, and can be beat in under a minute. Kill him, and get as close to the location he was last at when he died. If you are in the correct location, you will pick up all of the money he spits out.
 

Beat a boss and collect all the gold coins. When you finish collecting them, immediately use a Rewind. Most of the coins will return, allowing you to get almost double the amount of gold.

Beat the Forgotten City Boss:
Use the water in the middle. The Boss for some reason cannot go into the water. If you are in there, you can get to the correct location and hit him from behind.
