Hi Melimeli :)
Tiles are all 16x16, then scaled to 32 and 48 sizes.
If you want to have a clearer opinion on those assets, I have 2 solutions :
- Take a look at this free pack, which is from the same collection : Super Retro World : Interior pack
- Try out the free demo (playable in browser) to see how the assets can be used together : Super Retro World : demo pack
Habe a good day anyway !
