This was a childhood favorite of mine, especially given its a sequel to the first one, which I also loved. A really simple, yet fun game with a unique concept that felt kinda like making a paper airplane go as far as possible. Even once you got everything, there was still that strong desire to just...go farther and farther.
Then, you'll realize the secrets as a result. Overall, this game is really worth the time to dab in, especially if you wanna play with a friend watching, 'cause working together to make the most progress is truly a rewarding experience. I dunno how many times I finished it personally, but I tend to revisit it every couple of years.
