Training Room (Dark Mode) by mawwwk with credit to soopercool101 for the pillar addition, and PMDT for the original stage [Stage - Texture - Wi-fi Room]
Made for practicing ledgedashes on a late night.
Feb 2022 update:
Stage resized to match Battlefield's size and angles (this was originally intended, but I messed up somewhere along the line). Darkened platform texture slightly.
