Last 5 is a nice little game with a very interesting concept on which you can definitely expand later. Though I had to finish one "match" to understand that it was meant to be played in two. Sadly it doesn't have any sound effects, which could easily be made with an app like bfxr ( https://www.bfxr.net ) and some music for which you could use something like beepbox or bosca ceoil .
Nonetheless, it is a fun, puzzle like game!
