Run From An Underground Drill

Although I am extremely tired right now, a minute is too long to have to search for the "start" button. I assumed the header was just a flashy-animated thing. That being said, the screen is also quite small. When I died I could hardly read the credits that display.
The gameplay is similar to many other runners, but that isn't exactly a bad thing. You didn't clarify if this was your first game, but if it was, this was very good. Better than what most people can produce their first go at it.

I think my advice consists of the following: Make the screen/UI elements bigger, make the game frame stand out on the page, and maybe provide more collectibles/coins/crystals. It feels rewarding to the player when they feel like they truly accomplished something.

EDIT: I forgot to mention, the concept of being chased by a drill underground is also a great idea. I liked that part a lot
