Human Factors
We were taking off at OBE Runway 32; when we were climbing about 200 feet we saw on the GPS that we had traffic coming inbound direct to crosswind at 1;000 feet (that's not a normal procedure to enter on an uncontrolled airport) and he didn't report all the steps he was doing. We report our position in the airport's CTAF to verify he was on the frequency and he was; then he answered 'Affirmative' after that we kept climbing until about 500 feet then leveled up because of the traffic and asked him what he was doing and he answered 'I'm following you' he crossed above us just within 100 feet vertical distance.
Pilot reported an NMAC while departing the traffic pattern of non-towered OBE airport when another aircraft entered the pattern using non-standard procedures and not communicating their intentions.
