140 is a platformer puzzle at a glance, but when you invest more time in it, it so much more!
I've played a lot of rhythm based games, and for most (if not all) of them, the rhythm part is a gimmick. It's basically a shooter with enemies popping up at the beat or standard platformers where you don't really need to pay attention to the rhythms to succeed.
In this game understanding of the beat is crucial for success. I for one felt truly thankful for my time as a drummer since it helped me tremendously through the harder parts of the game.
There is so much detail put into the puzzles where you really learn to predict patterns and movements if you listen carefully to the music.
The graphics are simplistic but very functional. It's very clear how you must traverse the obstacles to proceed.
My only gripe as it stands is that it's kinda short.
Also, if the devs decide to work on a sequel, make more songs instead of just the one. Maybe 1st stage = 120 BPM, second 130 and so on.
