Forest were second-best for much of the contest, but stood firm to come to ensure they did not come away from the Amex Stadium empty-handed.
"We'll take our point and move on," said Kelly.
"We didn't get a foothold in the first half and when the break came the message was to get higher up the pitch and closer to them.
"We had chances either side of half-time and in the second half we got on the front foot and did a lot better.
"Brighton had opportunities in the first half but we nearly scored ourselves and the second half was much more even."
Kelly is convinced Forest are heading in the right direction after suffering a few spells of inconsistency.
He added: "Our squad was put together quite quickly and it takes time to bed in.
"Sometimes you're lucky and you just take off. We're trying to build it sensibly. This is a tough league but we are building ourselves up to go anywhere and compete."
