I didn't mind so much that you gave it a low score, I just wanted the criticism to be moe constructive so I can improve the game and learn form it for my next games. This is my first so it's a total learning experience for me. Thanks for playing it though! Here are some instructions I've included in the game notes till the next update for new players. Maybe it'll help you too.
At the start of every level, scroll around to see where the bones are that Demmy needs to collect. Then tap Demmy and he is ready to roll! Press and hold your finger on the screen to aim Demmy where you'd like him to launch to. Each time you press your finger on the screen, it will stop Demmy where he is (on the ground, mid-air...it doesn't matter he will stop!) and where you let go is where he will reroute to. This can be done three times. After three launches, he'll be dizzy but hopefully he'll roll to the coffin and complete the level!
