I am assuming you were inspired by Hollow Knight ? (I've never played it but silksong seemed similar in many ways).
Overall I like the art, especially the color schema and some foreground bringing some immersion. I think the dash works really nice but there were some small issues here and there, like not very clear what to do or that red box isn't a moveable object but rather an enemy. Another thing that was a bit annoying - on the start, when you reached top left (first) platform, you run "cutscene" or dialog which kinda stops you immediately from whatever you were doing (jumping/stopping/running). For my taste it was a stop with a bad timing where you lose focus. Additionally, I think you could have boosted the overall presentation with another font that fits more into your theme or even a cactus theme but I'm assuming you just didn't have enough time for that :)
Bottom line is, the game is interesting and I like that you put some story into it and it has some variety (based on screenshots). Great work.
