Léto s Oskarem (English: Summer with Oscar) is a 1998 Czech adventure game authored by Pavel Širůček and distributed by Vochozka Trading.

Two friends, Petr Vochozka and Jan Kudera, decided to set up a gaming studio in Brno, which they named Illusion Softworks.

[6] The graphic designer was Tomáš Svoboda, who also created the comic book in the enclosed manual; he also contributed to the previous game Hidden & Dangerous 1, and would later work for Pterodon.

[6] In this "a typical Czech comedy"[2] adventure, the player takes control of Oskar Sláma, who is so bad at school that his parents send him off to live with his grandparents in a rural village of Kotěhůlkách.

[2] In addition, the magazine argues it's one of the less difficult Czech adventures, and that the game contains outdated humour on groups such as women and homosexuals.

[2] Excalibur thought the game was a failure due to failing to deliver on their promised features and for being graphically outdated at the time of release.

[3] Vision Game deemed Oskat Slama a mixture of America's Leisure Suit Larry and Polish character Agent Mlíčňák.

[15] Vizuálny štýl českých a slovenských adventúr medzi rokmi 1990 až 1999 felt that while the game often goes for visual realism, it sometimes slips into cartoony graphics in the style of 7 dní a 7 nocí, and noted that the game mechanics were far from the quality of foreign titles such as Broken Sword 2 (1997) or Monkey Island 3 (1997).
