City of Amber is an action/horror title designed to play similarly to a 2D version of Bloodborne or the Souls series. The combat is focused on a dodging, blocking and attacking system that all runs off of a stamina gauge and revolves around the use of guns and melee weapons. The world itself is a dark and dreary place full of monsters, puzzles and exploration. Lily can be upgraded by using EXP acquired through combat. Upgrades consist of learning new evasive maneuvers, increasing attack power, learning new melee combos, increasing firearms effectiveness and improving stamina.

Looks great. If you want to use png, note that there are tools to make them much smaller (file size), without needing to drop the resolution. eg Tinypng.com. You can save much more by using jpegs, and can trade off size for quality - default settings save tons of space but can be a bit nasty.
