I've actually gotten some enjoyment out of speedrunning this. Because the bomb is fixed, I just memorized what I have to do. My PB so far is 0:22

I generally liked it. I agree with a lot of comments here, so I'll add something new. The reliance on color makes this game less colorblind friendly. It would be nice to add a secondary indicator to the wires to help colorblind people to be able to play easier.

Also, it feels like this game needs a randomizer for the bomb. That way I could get something out of replaying it.

this is real adrenalin, I think that i losf many lifes ..

A very good and intense game! Although I initially had some difficulties in understanding where I can cut the wires. And instructions for finding out the country by code should be somewhere else, because I found it only when I finished defusing.

We made a simillar looking game for the jam! Nice to see a concept twice but executed differently :D Sadly I can't open a .rar file

This is interesting, I would guess that it took a lot of inspiration from Keep Talking and Nobody Explodes. (If you haven't played it then definitely check it out.) Having it as a single player game makes an interesting different experience. 
I found I was able to 'throw away' my lid which meant the game was unfinishable. I don't think every game should be holding your hand but to accidently nudge something aside that you need is frustrating, especially as I had noticed the numbers and was trying to place it where I could get to it later. 
I also found it was difficult to read in places. I imagine that anyone with eyesight problems or dyslexia could find this impossible to play. 
I found that the beebing noise, while I understand why it was there, was very annoying. The volume not turning it down was also frustration. It actually made me laugh a little but the game was uncomfortable to play. I can see why you might have chosen to include it to add a forboding tension. 
The dial was swinging very fast and that caused me to fail a couple of times. It's a shame because this is the only place that co-ordination and dexterity are needed. 
My biggest issue was with the map for the location of the bomb. I think it's really unfair and immersion breaking to have to come out of the game to look up the answer. 
I hope that you go on to develop this further as it is a cool idea to have a 'Nobody Explodes' game without needing another player.
