One of the most popular trailers that debuted at this year's E3 Indie Showcase (at least according to a poll conducted on IGN's stream) was for Neko Ghost, Jump!. The game is a feline-led puzzle-platformer that features a mechanic similar to Super Paper Mario where players can shift between 2D and 3D perspectives.
According to the game's Steam page, it will feature 40 levels across eight different biomes and 100s of different ways for you to customise your new cat friend. There also appears to be a competitive element to the game. The new trailer appears to show a Crash Bandicoot-like time trial mechanic and the Steam page notes that there will be leaderboards present.
No exact release date has been set, but Neko Ghost, Jump! is said to be "coming soon" on Nintendo Switch, PC, PS4, and Xbox One.
