2d Approach Question

I have a question about how to best approach something in Unity.

I’m attempting to build a simple 2D word find type game (grid with letters that has words hidden in it). What would be the best approach in doing this? I’m looking for this to run on desktops as well as mobile platforms.

I’m looking at possibly 100 - 200 tiles.

I want to be able to drag the pointer (finger/mouse) across the tiles and have them light up until the player finds a word.

I have a grip on the algorithms involved, I’m just curious what’s the best approach for drawing the game surface using the engine.

Essentially, I guess it need to draw a number of tiles with arbitrary letters printed on each tile. Tiles need to be individually responsive.

Should I use the GUI system?

Should I try to make each tile a quad and just set the camera appropriately? If I’m going with quads, should I use textures with letters printed on them to texture the quads?

Thanks in advance for any pointers.

I would simple make the tiles cubes and use an orthographic camera. As you swipe your finger swap the texture over to the wanted result.

If that was too slow, then I’d look into going more low level.

Note: Not a mobile dev.

THanks! I’ll give that a whirrl.
