Ok, so what I have done is split the big matrix into 8 smaller matrices, 4 rows of 2, and am currently working on making movement happen. my head, for whatever reason, doesn't want to do movement The problem is, while the game does run faster when rooms aren't being loaded in, the program itself is 4 times the size of the original one, and is verrryyyy RAM heavy… but the RAM was true with your other one, too, so that isn't a concern. This is just so you know that It might take me a bit longer, as I want this to be smaller before uploading it.

As Of May 12, I have made it down to 947 bytes, compared to what you have, which is 390 bytes. It also uses 10467 bytes of RAM for 9 8x16 matrices, 8 of them for rooms, one for the current room in use. Here is what I've come up with to make the game run faster while in rooms. Room making and loading is going to be slow no matter what I do.

Can't remember how to do a hidden block

the Gotos that I have shouldn't cause any memory errors. If you have any questions, just ask!

As of May 13, the revised program is 747 Bytes of information, with the matrices taking up the same amount of room. This should be the last update I do, as I can see no further optimizations
