1. You don't necessarily need PGE to use steep slopes. It does make it slightly easier. But there's a simple technique that involves swapping blocks and a SMBX bug that will not change the block's hitbox upon swapping.
2. Your blocks incorrectly use the Super Mario Advance 4 palette, meaning these aren't compatible with SMBX 1.3.0.1. I shouldn't assume everyone is using our update but a good portion does and hence it would be nice of you to recolor your blocks to match the tileset in 1.3.0.1!
3. Lastly these particular tiles are actually used in the overworld in SMB3. The ones normally used in caves like you are in your screenshot look quite different.
Good job though :P
