You control the cute Cool Coyote who's quest is to go through eight worlds in pursuit of the evil wizard Suten. In each level you collect pieces of a key which will give you access to the next part. Those pieces can be found via monsters which will drop pieces of the key when killed. Attacking a monster works by shooting ice pellets at it. Note that this causes no damage though, but only will freeze it for a short time after having received enough hits. Any monster can then be killed by touching it as long as its frozen.
There are also, there are hidden warp gates that will transport him to other lands and possibly hidden bonus zones. The game is a cute but difficult jump 'n run platform with pretty sensitive controls, so that you'll need quite a bit of manual skill to get your Coyote where you want him to be. Nevertheless, it's a fine arcade platform, with huge of playability!
The Amiga could display 32 colors on screen at once, or even 64 using it's unique special Extra Half-Bright mode (EHB) or 4096 colors in static screens. But copper effect (Amiga hardware only) offered something more here: Each on the two screens (one for the gameplay and one for the map) used multiple copper raster-bars effect to give the graphics (i.e check the sky) a colorful gradient. With copper palette it is possible to manipulate a change in the reflection colors and thus more colors can be depicted. So the effective number of screen-colors here are 100+! The graphics look very good, and the animations of Cool Coyote and his adversaries are just great. Both foreground and background scroll smoothly, so there's no annoying flicker or anything. It is quite noticeable (and Amiga only) the impressive shimmering water effect at the bottom of the screen (the second screen - control panel mentioned above). Note that the Amiga version(s) features much foreground and background detail of various graphics, in contrast to the ST/STE (which by the way offer 70+ and 90+ colors on screen respectively with special - but unknown to me - techniques!). Also note that, due to enhanced memory and CPU, the A1200 and CD32 versions (AGA chipsets) sports extra detail here along with 256 colors on screen compared.
A far as the sound, Amiga offers a great main menu music, as well as in-game SFX and great background.
