No, thanks, I hope that I'll figure it out myself in month or two

We plan to update in next 5-9 month. It takes a very long time to transfer sprites manually, and I'll have to transfer each one so yeah. 

Sorry for late reply. 
Go to Steam, find Nuclear Throne, right-click on the name of the game, go to "Properties", then to "Beta Versions" and click on "ntt_development - NTT test build"

Hello! Check your version if you play on NTT. Texturpack doesn't work on any other versions except 100.017. Also it sometimes can give fatal error if you play in multiplayer.
