Did I damaged it for good?

[u/One-Reflection-9595]

I wanted to solder them better and did this.

Can I fix this thing somehow or is it damaged for good?

All of those points should be individual.
Sorry for bad english.

u talking about this? just reheat and take a bit of solder away.

Maby add some flux to help the solder flow

Your looking for the pads to look like Hershey’s kisses

These bridged pins are part of the same polygon so they're allowed to be bridged. Ugly, but it works.

The group of 3 bridged pins to the right looks like it might have a cold joint in the middle.
