Overall, the game is good. My only complaint is there is no secret counter to keep track of all the secrets that you have found (for example, the game has 100 secrets and you have found 95 of them then the secret counter will show you that 95/100 secrets have been found. That means there are 5 secrets left you need to find). This will reduce the amount of times that you have to replay the game or backtracking to previous stages to find all the secrets because when you don't have the exact number of secrets to be shown in the game. The players might think that they have found all the secrets so they proceed to go and defeat the boss and then the medal didn't pop up because they haven't found all the secrets.
