The game is an action platform game that scrolls both horizontally and vertically.
On each of five stages you'll need to fight various enemies throughout the varied terrain, and finally defeat the boss at the end.
You'll start with just a simple sword, but additional weapons can be found or bought in order to help you out.
If you get into trouble, you can also call your dog Zap onto the screen; he'll jump around causing damage to the enemies giving you a chance to escape.
You may also come across Kim's shops along your journey.
Here you can buy various items, including additional lives, replenish your health, more powerful weapons, and other useful items.
To purchase items, you'll need money which can be collected after defeating enemies in battle.
About Nintendo Entertainment System
The Nintendo Entertainment System (1983 in Japan, 1985 in the West) revived the North American video game industry after the 1983 crash and established conventions — cartridges, licensing seals, save systems — that shaped the industry for decades. NES collecting is one of the most established retro markets: common titles remain cheap, but a well-known handful of low-print-run games (many from smaller third-party publishers) are among the most expensive video games in existence.
Gamevaro tracks Conquest of the Crystal Palace for Nintendo Entertainment System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Conquest of the Crystal Palace to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NES release dates back to 1990.
