Tomb Towers

Description
Tomb Towers is a puzzle-platformer inspired by MSX games, featuring visuals and play mechanics modeled after the era.
An evil necromancer has unleashed a horde of monsters and skeletons upon the land. A lone traveller happens to find a suit of armor and decides to stop the necromancer, finding a hidden entrance to the necromancer's tower through a nearby well.
Each level requires grabbing a key to unlock the exit door. Each level also has one or more relics, which can be collected to unlock extra levels.
The levels are increasingly tricky, however, with spikes, flames, crushers, moving platforms and other dangers - as well as the necromancer's skeletons and monsters - in the way. Reaching the exit often involves pushing boxes to act as make-shift platforms. The knight cannot attack directly, but some enemies can be defeated by pushing objects on top of them.
The tower consists of 45 levels, plus 15 unlockable extra levels.
