As far as I know we don't pronounce "g" in ing endings:
Playin', movin', talkin' etc.
Do we pronounce "g" at the end of adjectives?
Temting (temptin'), appealing (appealin'), fascinating (fascinatin') etc.
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

No, that's wrong. The sound at the end of 'ing' is /ŋ/ not /n/.
The use of /n/ here is sub-standard in AusE at least, and non-standard in most other places.
