1. Make sure you’re using nearest-neighbor for scaling otherwise you end up with blurry aliased fringing on assets that are supposed to represent pixel art.
2. The character is moving left to right - why are the oxen on the wrong side? Are they pushing the cart? :)
Same thing occurs when you die of "tech debt dysentery". The oxen is on the left side, but the wheels are rotating clockwise.
3. On a widescreen monitor, make sure to wrap the text section; otherwise you end up with lines that are far too long.
However, if you’re using pre-rendered sprite sheets, you’ll probably need to enforce integer scaling to avoid fringing or blurring.
