Another indie title with insanely glorious visuals, Insanely Twisted Shadow Planet is a side-scroller with Castlevania-like map which encourages both exploration & backtracking.
ITSP's map has insanely plenty of collectibles from upgrades to artworks, it also has an insane arsenal of weapons some of which are required for campaign progression. ITSP also features insanely huge bosses with insanely creepy figures & attacks.
Grab this one along with Botanicula if you are taking a break with the usual high profile games out there.
