In my opinion, there is nothing wrong with the actually puzzles, but there are a number of things wrong with the game
- It appears in a very small window of the gaming screen. If it is actually this size, you can fix the presentation on Newgrounds to conform to this, as people who have made games as small as this have done it as well.
- After the first level in World 3, the game goes to the loading screen and nothing comes up after it (I was waiting for at least two minutes for it and it just stays there. This has happened twice).
- Sometimes in one square high corridors, it refuses to let me go through or fall. I have to back up and then go through them in order to get through. This wouldn't be a big problem except for the cases where you are falling. If this glitch happens to just one of the characters (which has happened to me), then you have to restart since both of the guys cannot go outside the game window.
- Also, the first level of world three is interesting in that there are multiple paths you can take, but I needed to find a specific one because of the glitch I mentioned before due to falling.
Other than this, I thought the game mechanics were pretty good, as it forced you to find ways to regroup with your friend. Hope that you fix the problems I mentioned and I hope to see more from you. Good luck.
