Thank you for all this awesome Feedback! I really appreciate it and will definitely be working on the points mentioned in here.
For what it's worth the secret in Level 1 is the Dragonball on the far right hand side of the map which can be reached by following the top route all the way to the right where there will be invisible tiles that become visible upon collision. Push it into the water to activate the Easter Egg,
Level 2 requires 2 coins which can be found inside the boxes if you collide with them (Like Mario) - 3 Coins unlocks a pipe on the top right hand side of the map which takes you to a secret level,
Level 3 just requires you to activate 3 torches and the make your way to the far right hand side of the map to finish it.
I'll try and make it more clear like you mentioned.
I'll also make everything else a little more user friendly :)
Thanks again!
