Hi, thanks for trying our game, I'm sorry that you weren't able to launch it. The itch client currently does not support LÖVE2D games, that issue can be tracked here: https://github.com/itchio/itch/issues/135.
The game requires LÖVE version 0.10.1, it will not work on any version of LÖVE 11.x. If you provide me with further details, I can assist you further.
