Python is going to chug even on relatively simple action games. I did write some 2D stuff in Pygame/SDL and Pygame/OpenGL back in the early-mid 2000s that could do 30FPS, but to do it was akin to writing in BASIC on an 8-bit; you had to micro-optimize in a fairly brutal way, one which obscured Python's powers. Things like rendering a tilemap could get huge speed boosts simply by avoiding nested loops in favor of a cache. Even using OpenGL wasn't really enough to secure a comfortable margin of performance.

If I did it again I would have an easier time because I missed a few critical constructs back then(most notably, the array package). It still wouldn't be pretty, especially not on a phone.
