No gain? I think inproving the graphics of the game would be very cool.
Every graphic proposal is answeered with "i dont think its useful nah".
Maybe ur right, one single upgrade isnt useful, but one will follow another
Considering the ( fairly ugly D: ) water graphics we have which is just one tile that's an animated gif or something like that, I really don't think it's possible to do that anyways.
The water tile is made of 33 animation frames and is by far the tile that requires the most space. Making a version with starts on it for every of the 33 animations wouldn't be really cool...
It wouldn't look nice and it would take a good amount of wasted space in the memory.
