I've created more than a few experiments like this using dc<%> backed by canvas% or bitmap%. For such simple game like you mention, it will work like a charm. However it is not the fastest approach - I remember rendering a Rubik's cube last year for the students[1] and on Linux it ran fluently, on Mac it ran at 2 frames per second for no apparent reason. Probably the Cairo back-end is just really slow there. I would assume Pict is on-par with dc<%>-based approach (in the end that is what renders the rasterized image). Funnily enough, I am working on a graphics side project right now and I have a working 3D rendering pipeline completely in Racket which works surprisingly fast even on 2560x1440. I plan to publish a series of articles about that. No OpenGL, no compiled C code, only Racket trickery. Or you can use ASCII (as seen on RacketFest 2020)...
