Here are the hidden powerups and boss tactics for stage 1 to 3. Stage 4+ are huge labyrinths so I'm not sure how I will write info about those.
Stage 1-2
- as you enter, on the right ledge, above sight. (Monster Level)
- just below that, on the second ledge, you can go behind the pillars with a jump. Note that you can exit the area by falling down on the left side directly, instead of tracking back to the right. (Monster Level & Food)
- 3rd ledge on the right: Make sure you hold Lightning while jumping if you want to get this, since a badguy pops and hits you mid-jump. There is no way to backtrack here. (Continue item)
- 4th ledge on the right: You can climb the second pillar with high jumps (Monster Level)
- In this very chamber, theres a hole on the upper right corner. (Lightning Up, HP Up)
Stage 1-3
- as you enter, straight walk to the right side, ignoring the stairs (HP Up)
- After you climbed the stairs, theres a detour to the far left, filled with gargoyles (Lightning Up)
- Once you are on the other side of the building, go back to the building, you can destroy the wall with your rolling blast on the upper level of it (HP refill)
- On the lower floor, move to the left, next to the wall as possible, an extra item will turn up (HP refill)
- Move to the right from this spot for 3 more items. Watch out, as you move to pick them up, boulder-droppers appear above you. (Monster Level)
- Take the upmost route and theres a hidden location above the boss pit (Monster Level)
- Boss tactic: move to the far right, turn around so you face to the left. Have the Ball O'Fire selected. As the boss comes in, move left so the fireball is positioned EXACTLY overlapping the boss - this should kill the boss in 2 hits if the ball o'fire is lvl3. Then move to the left, as close to the other boss as possible, and use the rolling blast directly in its face - it should die instantly as well (lvl3 lightning).
Stage 2
- As you enter, move to the left corner, there is a hidden item box (invincibility)
- In the Sea Lizard pit, there is one hiddem item in the leftmost corner, and one hidden item in the right side (but not as far as the right corner). (HP refill and Monster refill each)
- Additionally the Sea Lizard can be defeated on its very first pass, if you do a well timed Rolling blast in its face, with the Thunder Lizard helping out (you need high levels for this, I can barely get it done on lvl3 lightning and lvl2 thunder lizard)
- Right after the fairy platform, there is an extra item hidden above sight (Continue)
- There is one Monster Level item directly on your route.
- At the second Saucer attack (the one guy that comes in alone), you can ride his saucer to reach a hidden spot.
- Once the saucer guys come in, you can drop into the pit for extra items on the far right (HP Up and Monster Revive). You can exit via platforms on the far left, which also has a HP Refill. The pit is filled by tons of frogs.
- Boss tactic: Move as close as possible (you can almost overlap its mouth) and use a rolling blast when it opens its mouth. You'll need to duck in the middle of this, or you will get hit, and the hit stun will make you miss the rest of the rolling blast. If you can get the full rolling blast in its face uninterrupted, it will die INSTANTLY. Failing this, if the Thunder Lizard manages to fire as the boss has its mouth open, it should die the 2nd time it opens its mouth. (lvl3 lightning, much easier with lvl4)
Stage 3 (note: this battleship is titled "Barunga")
- Once you cleared the turret area and killed the saucer guy, don't go up. Move to the far left, back to the engine (Monster Level, Revive)
- Once you moved to the main levels, above the HP refills there is an extra item (Monster Level)
- Directly above you in the same location, another item is hidden above sight (Infinity Lightning)
- On the main levels, on the lower left corner, there is a hidden item, you may need to jump for it to appear (Continue)
- There is a Lightning Up item directly in your route as you jump up on the left side.
- Directly left to the Lightning Up, there is a hidden item (Monster Refill)
- Boss tactic: ???? I don't know how to insta-kill this boss. The middle horseface can be killed with a rolling blast instantly, but the other two are too far away for this to work. The dragon does a remarkable job at killing them though.Move to the rightmost corner and turn left, the dragon will automatically fire to the other way, and this way its close enough so all 3 of its fireballs hit the horseface thing. If all 3 fireballs hit, it takes 2-3 salvos to kill one of the horseface things. This leaves the one on the far left, no clue whats the fastest way to kill that one.
