• ​No save or password save

• No continues without a code (and you need to beat the first boss first to be able to use it)​

• ​Partially non-linear structure (can choose between 2+ (4 on the second and 7 on the third floor) levels/sub areas at a time in the overworld/outside the castle)

• Few exploration/movement oriented upgrades (one transformation (mini form) via the potion and the gloves placed in some areas (temporary - go back to normal after exiting the current level/sub area), fire protection vest (protects for a few seconds at a time), the two pairs of jump shoes - only the first pair is really needed to progress, the lamp to see in the well, the blimp - hover jump, paint - to see the invisible platforms in the shrines, the feather (use the elevator platform) isn't needed)

• No area maps (the NES manual shows a basic exterior map and names the first few rooms)

• ​Buy items and healing in shops with money collected in the levels (can also get clues for free though they tend to suck)

• Can replay beaten levels

• Weather mechanic with an effect on gameplay outside the castle (lightning storms)

• Frequently respawning enemies (they tend to be easy though)

• Life bar upgrades (honeycomb item), Upgradeable shot power and range (lvl 3 also keeps going after destroying something), Temporary rate of fire upgrade (umbrella item) - lose one upgrade when hit enough?, Temporary shield power up

• Some decent platforming puzzles

• Quick "exit sub area" item (balloon) - however you can't put it in your inventory for later use and you can only find one in the well
