Great game!
I feel sorry for you that people who don't know how to play the game are giving you horrible reviews! I strongly suggest to have a tips/tricks page because your game doesn't deserve some of these negative reviews. This game is actually pretty easy if you just use your noggin a little! You can't jump straight out of the planet and leave yourself so vulnerable for so long people!... Try smaller jumps! Another good thing to do is to wait for the upgrades. Every time you leave the planet a new upgrade will spawn within seconds. After you use and upgrade, stay beneath the planet for a few seconds and wait for the next upgrade! Also, try maxing out the worms damage and a few points in health first.
If anything, this game could use a harder difficulty. Add a tips page also and you have a great game! It's pretty funny to read some of these complaints...
