Hi! Thanks for the feedback, and that's why I made some changes! :)
- Pressing Enter starts the game and try again.
- Pressing Backspace returns you to the title screen.
- Decreases the time between Rounds so you don't have to wait so long.
- I removed the heart at the top, because it's just one life ;P
- Changed the name "Game Over" to "You lost".
- Removed an annoying "onclick" error.
That's what I could improve, Thank you ;)
