everything in this short sweet game works really well.
especially like how you pace the early levels with the simple 222 , 311 sequences which are easy and satisfying to get quickly.
i had to play without numpad so i had to rewire my brain for this one, it was fun improving my times.
depending on how important you think it is for players to know how much time is left in a level i would either put the clock down lower so u can see while typing the number or having an audio cue because i think most ppl including me would be too focused on typing the numbers to pay attention to any of the top UI.
also now I'm curious how the game would feel without the need for backspace, like if wrong inputs get immediately removed and play a sound queue (there's also a time loss element here so ur not being rewarded for spamming). Not sure if this would be an improvement but it would remove some complexity so you could just focus on the numbers.
