A nice mix of very well made minigames! It was confusing at first as the 5 second is just enough to get used to a game, but it is over already! I think it could be tested to have a rotation system of 2 games for 10 seconds so you can play along all these little awesome gems for a few more seconds each run!
Also, thanks for the sound options! Sfx nice, music was a bit too quiet on the base but with the tweaker that can be solved! Pixel art is nice and crips, well done!
