It is a platformer in the same vein as Spelunky, minus the rogue-like qualities. The objective of the game is to lead the titular Tobe to the bottom of a cave, collecting power ups and jewels, and saving chickens, along the way. When you reach the bottom of the cave and open up the giant treasure chest that awaits you, a countdown timer begins and you must make your way back up to the top of the level before it caves in on you.
Here is the official trailer and a gameplay video for those who may be interested.
I am having a ton of fun with this game right now. It's scratching my platformer itch, much in the same way that Breath of Death VII, another XNA game, is scratching my RPG itch. If anyone has played, or is playing this game right now, let me know! I am really enjoying it and would love to discuss it.
