Thats whas great!, it's a really fluid and polished game, look pretty nice too.
Thought, it confuse me a little you can end with a negative score.
And there is the spikes minigame, it's excelent to combinate with others as made them harder , but for itself doesn't work all the others incite you to move. I would use it as penalty instead or as a extra condition in a harder dificulty.
Simply compare it to Rain and Bullets are in a point they are easy enought to incite you to find another egg, but you can't stand still with them if they are the first minigame you trigger. the others the Eye, Treadmill, Coins and Flags require you to move to finish them.
