Well, Applez was a nice game, even though the collision detection was crappy at times and the hit recovery time was annoying. Other than that it was fun and had a cool endboss. Well, a save feature when you close the game wouldn't hurt anyone either.
I don't know if it has been posted before, but here's how to get the Collector medal on Applez:
Level 5: See the red button at the start of the level? Press it. Use the Slime Cats to get back to it while you're fat, then climb the platforms and collect the extra life.
Level 7: To the very right of the level is a gray wall with an extra life behind it. To lower the wall go to the apple at the top of the level, eat it and then go right until you fall very deep and land on a button that lowers a bridge. Then go back to the apple at the top, eat it again and drop down to the right again. This time you land on the bridge. Go to the left and find the gray block. Push it into the space between the bridge and the flag and follow it. Go right, step on the button, collect the extra life.
Level 10: From the start of the level, make your way to the right until you reach the moving spikes that point upwards and move vertically. Drop down where the spikes move (when they are at the top) and you should find an opening in the ground. Drop down and you land next to an extra life. Collect it.
And as an extra, here's how to get the Jump, Magic Jump medal:
Go to the left where you found the extra life in level 10 to find the Golden Bounce Pad, or just drop down to the left at the start of level 10.
