Indeed, we are to have fun brethren. Be careful tho, that you may not be indulging with what makes you fall, or for you to give yourself what is pleasing while feeding the flesh or even worse, while drifting away of The Lord. Now it comes to my mind one truth which is that we don´t really deserve anything from God as He does not really ows us anything but vice-versa, as it is, we are guilty of judgment because of sin but it was because of the blood of Christ that we were cleansed from it and given The Holy Spirit and grace, and in this, watching the grace of The Lord being poured to us despite not deserving it we also are able to see that even while we were sinners, we were already blessed as the mere fact of going out to the park or being able to sit and have a meal were gifts from God. Secondly, there are things which God intended for us to enjoy while we are on this earth such as having sex (in marriage), eating, sleeping, creating (art, engineering, writing, producing, etc), and even other things which we tend to not so pay much attention to such as "traveling" (moving to wherever we want by wheels or by foot which is pretty neat honestly), and so on.

But do not use your freedom to indulge the flesh; rather, serve one another humbly in love." and here a word he expressed to the Corinthians (a church in Corinth-Greek city) 1 Corinthians 10:23 “I have the right to do anything,” but not everything is beneficial. “I have the right to do anything” but not everything is constructive. Let us enjoy the pleasures God arranged for us on this earth while keeping Him, at least in conscience through His word and the putting of the whole armor of God:
