I used FLStudio to make it. It's a pretty steep price point though... You can use the trial for free, but you can't save anything in it. If you want to be able to save it'll cost anywhere from 100-500 USD. Realistically though, the minimum is about 200 since you lose a lot from the trial if you only get the $100 version. Beepbox and garage band will probably suit you well for a free DAW. Otherwise, soundtrap is also free, but kinda overused, so a lot of people might recognise it. Glad you liked the song though, I'll probably upload it and the title version of the song to my YT at some point in the future.
