haha, it is pretty fun. some minor suggestions,
1. I hope the combination can be put in the help so I can check it and try to remember the combination I want before playing.
2. the game relies on randomness too much I guess, if you can't get a good sequence of dots, it might be too hard to finish the level(or I'm just not good at it)
3. Did the combination list missed some color? I feel I got a combination like blue green and get healed, but I don't see that in the combination list.
4. After getting speed up, the movement is insanely hard lol. It's like moving on ice.
All in all, I like the concept of it and good job!
