Hi there I'm developing a pixel art 2D platformer for pc and smartphones but I'm stuck on a techincal issue. I chosed to have 32x32 pixels resolution for the tiles, and 64x64 pixel resolution for the character sprites. In the game I have got a double-jump like mechanic so I need to have a good vertical view range on each "screen" (about 20 tiles). The levels are divided in sections that I call "screens" and in each screen I've got 40x22,5 (approximated to 23) tiles, so the minimum resolution is 1280x720. Here comes the issue: 1280x720 is not a very high resolution so the window in HD monitors would be not so big and if I upscale the resolution I will go in 2560x1440 and the window would be much larger than an actual HD monitor. If I try some sizes in between of 1280x720 and 2560x1440 the graphics starts to stutter or is deformed. How can I solve this issue? Is there a solution that does not require me to redraw all the tiles and the sprites in 16x16 format? Thanks in advance.
