おまけに is a conjunction meaning "on top of that," "to make matters worse," or "what's more." It is used to add further information that reinforces or intensifies what was already stated – piling on an additional fact that goes in the same direction as the preceding statement.
おまけに can be used in both positive and negative contexts, though it is especially common when listing compounding negative circumstances.
Negative context (to make matters worse)
When the first clause describes something bad, おまけに introduces an additional negative point, creating a sense of things going from bad to worse.
。。
I got lost. On top of that, it started raining.
。。
I forgot my wallet. To make matters worse, I left my phone at home too.
Positive context (what's more)
When the first clause describes something good, おまけに adds another positive point, emphasizing how favorable the situation is.
。。
This restaurant is cheap. What's more, the portions are generous.
。。
She's smart. On top of that, she's good at sports too.

- Unlike (which is more neutral and formal), おまけに strongly implies the speaker's subjective evaluation that the additional fact compounds the situation.
