I quite like the asset pack, the rogue-style assets are readable, cohesive and well laid out. I quite like the little skeleton enemy.
It would be useful for the asset pack to be in a single .zip download, as well as having sprites like enemies and characters on their own layers with transparency around their edges, so the empty black space around them doesn't block out sprites behind them. It's an easy but time-consuming fix for a potential user of the asset.
