Hi Jonnection,
I have a good news, I tried this game in 3 SD cads on my Gamebuino.
My first attempt was with the original SD card of Gamebuino (128MB scandisk) that it was very slow and not playable.
So I got another SD card (1GB Scandisk), I formated it and put the game and I played. The game was playable, much more fast that the firt, but it still had a small lag.
After, I tried with other SD card(2GB without brand), so it had a similar result with the second SD card. So I had an idea, I tried to change the unit allocation size (Cluster size). Both two SD cards, 1GB and 2GB, was with 16k cluster size, then I changed to 32k and I saw a good improvement, but it had a little lag. So I changed the cluster size to 64k and the game worked perfect without any lag in both SD cads(1GB and 2GB).
After that, I tried to format the Gamebuino original SD card, but unfortunately the maximum cluster size is 16k. Despite this, the game got a similar performance at my first attempt with the SD 1GB (playable with small lag).
"...using large A.U.S(Allocation Unit Size) significantly reduces the free space utilization due to not using the last allocation unit completely. And as a side effect, the number of files to store on the disk is reduced due to same problem, last a.u not being used fully. But, here's the trade-off, using A.U.S, significantly again, improves the disk reading performance. The O.S can read more data at one read. Imagine, O.S makes couple of disk reads to completely read a GB sized file!..
Using small A.U.S improves the free space utilization but reduces the disk read performance. Think using large A.U.S in reverse, same category problems and improvements, but in reverse..."

The problem is not with Gamebuino, the problem is the original Gamebuino SD card. So I will use another SD card (1GB or 2GB).
If anybody has a SD card that it can be formated with a 64k cluster size. They can play your game without lags!
It is a major evolution for Gamebuino games, because it breaks the limitation of space. =D
@Jonnection: I hope you continue this game, because it is very good!
Sorry about my english.
