Throughout the game you’ll acquire new tools required to solve puzzles such as a cat which you can use to hit switches from far away or an amp to blow up rocks. The cat is the most useful as you can shoot through enemies to stun them so that you may temporarily get away or go through them. Dali, the cat, can also open chests from far away going through enemies. In the towns or at vending machines, you can buy more healing items, equipment and weapons. Make sure to spend most money on healing items as you might encounter a stretch or two where you can’t get anymore. Buying new weapons didn’t really seem to improve the character’s damage output at all. Rather than experience points automatically filling to level up you must spend them at the mind dungeon. Via any phone booth which is also your save point, you can go in and spend one hundred experience points to level up.
