Within-Subjects ANOVA with low sample

Hello, I have some data that I want to analyse. It is 2x2 within-subjects design. My DV is continuous and the two factors have 2 categorical levels. But I only have 8 subjects, so I am unsure about how to proceed. Is it correct that there is no reasonable alternative to just using an ANOVA? If not, then what approach can I take with this?

If you want to analyse the main effects and the interaction, then you need to use repeated-measurements analysis of variance.

If it is enough for you to know whether there is a difference between the 4 conditions, then Friedman-test, and some appropriate
test for possible pairwise comparisons (Wilcoxon signed rank test, maybe).

With kind regards
