Trine and the heroes hope they can return home without starting a new adventure on the way. Development The Humble Frozenbyte Bundle, one of the Humble Bundles, started on April 12, 2011 and featured five games from Frozenbyte, including the original Trine, as well as the games Shadowgrounds and Shadowgrounds: Survivor. It also contained an executable version along with source code for an unfinished game, Jack Claw, and a pre-order for their upcoming game, Splot. By April 22, 2011, the Humble Frozenbyte Bundle had surpassed $700,000. Most of the money generated by the sale went to finishing the development of Trine 2 after it was suggested by lead developer, Mike Donovan, that a sequel be made. The Linux version was delayed from the rest to allow for additional development; it was the first Frozenbyte title ported to Linux in-house, with their other games having previously been ported instead by Alternative Games. Jukka Kokkonen, Frozenbyte’s Senior Programmer, revealed that the actual porting was actually "easier than expected", although he did comment that they had some trouble with testing. The port was released as a beta in late March, and is to be released on services including Desura and Gameolith. Kokkonen stated that he hopes that Trine 2 "shows that Linux can provide a proper gaming experience" and that they are "very excited to see how Linux users react to the game.” The basic porting process for the Wii U's Director's Cut edition was achieved by Frozenbyte in just two days, which gave the development team plenty of time to adjust visuals and implement the exclusive touch screen functionality, and subsequently made the game ready to be launched alongside the Wii U console launch date in all regions. According to Frozenbyte's sales and marketing manager Mikael Haveri, Nintendo's initial approach and close contact with their company helped support the process of releasing the game for Wii U, and subsequently made it Frozenbyte's first self-published title without the involvement of Atlus, the game's publisher for other platforms. The support for Trine 2: Director's Cut is cited as one of Nintendo's initial steps into reaching out to the independent video game development community. Haveri adds that working with Nintendo has been "very freeform" and positive. Expansions Goblin Menace expansion An expansion pack for the game entitled Trine 2: Goblin Menace was released September 7, 2012. It features six new levels, a new story, and
