Wow thank you!! For the checkpoint situation, we're planing to separate the tutorial from the actual level, so it's not as frustrating. For the timer, we understand it's kind of scary, but since you're trying to defuse bombs, it was intended.
For the theme of failure, originally, we wanted to make a game where you actually infiltrate the terrorists and disarm the bombs as they are planting them (to sabotage the mission from the inside), but the idea evolved and now it's not as fitting to the theme as it was.
