Monsti (Won on SteamGifts)

An endless running/flapping game with no achievements. Only allows you to swap to various flappy bird characters with various speeds using the eggs that you’ve collected in previous runs. Felt like a PC clone of mobile games like Flappy Bird or BADLAND. More suited to playing on smartphone or tablet rather than a PC. Average graphics and repetitive background music.

I’d suggest getting this for less than a dollar or avoiding this altogether.
