i beat it on hard difficulty and it was very challenging and fun to play and i wish you would make more games like this one, also i found that if you press c it will swap the control scheme until you beat a level or die and that if you press r the timer will be set to 4 secs, why not just make r reset you asif the bomb reached 0 because that would save you having to weight 4 secs between each attempt, and stop the infinite time glitch by spamming r.
