I always thought it meant how everything is implemented. Is there any bugs? Are the controls tight or does it feel like you’re constantly fighting to get stuff done?
An example from an entry I rated for the B&W Jam, the game I played had interesting and fun gameplay but the animations were glitchy and it was difficult to control due to poorly implemented movement code.
I rated the game with a high gameplay rating but a low technical rating because of that.
Edit: I was wrong. Directly from Lone Rabbit
Technically advanced. Does the game do something impressive on the programming side of things? Something like that.
