The main mechanic is interesting enough to make for a good game.
Others mentioned looking up common platformer mechanics.

The level order is fine. I like that different enemies spawn different platforms.
I wish there was some way to recover from bad placements other than starting again.
Making the summoned platforms turn back into enemies after a couple of seconds might be a solution to this.
This could also spice up the mechanics even further with linked enemies, where only one can be a platform at a time.
There is a lot that you could do with this mechanic. Given the time frame of this jam it's cool how much you were able to accomplish.
