As this is - no surprise - an unofficial version of the Popeye arcade game (Nintendo, 1983), you're probably already aware of the premise.
The aim is for Popeye, moving up and down the four levels on the screen, to collect hearts thrown down by Olive Oyl while avoiding Brutus. He throws punches and bottles at Popeye, and watch out for the Sea Hag who resides at the edges of each level. To defend against these two, Popeye needs his trusty can of spinach.
Despite the feature of the punch button, Popeye cannot attack Brutus or the Sea Hag directly. Punching is used both to destroy the bottles before they hurt Popeye and to gobble down the cans of spinach.
A punch bag is available, and when it's hit it releases a cage that - should Brutus be underneath at the right time - traps him for a few seconds, which gives you a bit of a breather from the chase. To complete each level, collect all the hearts.
It looks pretty, but it's way too hard to play. Due to Nirvana's constraint of moving only one character at a time, the sprites are too small to be able to avoid the bottles, Brutus and the Sea Hag.
It's also tricky to move around the play area in a way conducive to completing a level and I found myself missing the stairs that take you between the levels. I couldn't even complete the first screen despite repeated goes.
Had there been some proper playtesting before release, maybe the first screen might have been made easier in order to ease the player into the game more gently and Popeye would have been more fun to play. As it is, it's just infuriating when you lose life after life.
The music is grating: a single continuous in-game 128 tune that doesn't really go anywhere and uses only one channel. This is probably the best version of the arcade game on the Spectrum, but then there's not much competition.
