A sequel, entitled Horké léto 2, was developed by Centauri Production and published in 1999 by JRC Interactive.

Žhavé léto 3 ½ was published in English, Spanish, French and German as Evil Days of Luckless John and in Russian as Сорвать Куш.

Most characters, excluding some female ones, were voiced by comedian Zdeněk Izer, a notable Czech impersonator.

[2] Like many other domestic video games of the era, Horke Leto was intended to appeal directly to Czech and Slovak players.

[4] Horke Leto 2 caught the attention of Bonusweb during development, who devoted a considerable amount of airtime to the game.

[13] While developers from Centauri Production wanted to create a second sequel to the game, they were unable to obtain the rights for the name "Horke Leto" or the main character Honza.

[1] In Horké léto the player takes control of teenager Honza Majer, who must rescue his family after they are captured by cannibals.

Žhavé léto 3 ½ sees the player take control of Honza's grandfather, the hapless protagonist Johnny Majer, who must compete with the Mafia in the age of Prohibition.

[19] Excalibur stated that while the graphics and gameplay were nothing special, it was the dubbing into local languages that captured the imagination of Czechoslovakia.

[20] Refresher thought it was the 20th best Czech title, praising the game's amusing dialogues and first-class dubbing.

[21] In a preview, Bonusweb hoped that the game's humour would outweigh its average graphics and animations making it an above-average Czech title.

[23] Evil Days of Luckless John (Žhavé léto 3 ½) received mixed reviews from critics who enjoyed the game's artistic style and story but disliked its gameplay and interface.

[25] Adventures Planet noted the strange mix of genres, that saw arcade-style gameplay be followed by Myst-style puzzles.
