My toolkit is pretty much the same all these years:
- LibGDX, IntelliJ IDEA for programming
- Photoshop, Aseprite, PyxelEdit, MagicaVoxel, Wacom Bamboo for GFX
- BFXR, REAPER w/ tons of VST for SFX
- Tiled for levels (thought I used inkscape for level design once)
- Bitbucket as VCS
- LICEcap for GIFs
- OBS for video recording and streaming
