A few suggestions:

1. Make the map zoom in before the 3 second countdown for the next round starts and not after like it is now. It's annoying that you have to find your character after the round already started, even if it only takes 1-2 seconds. But 1-2 seconds can already mean you start with a big disadvantage. I want to know where I am immediately when the round starts.

2. Show the score screen of the final round before you show the overall winner of the match. It's weird that you see the winner of the match before you even know how many points you scored in the last round.

3. Give us an option to disable the bombs controlled by dead players. Rounds are fast enough imo that this isn't necessary. It's a fun option to have, but personally I would just disable it. I want the last 2-3 players duke it out on their own instead of randomly getting bombed out of (almost) nowhere.

EDIT: After playing some more this is an absolute must-have. The slight randomness in the game is fun, but not if you get bombed out of nowhere by a dead player bomb dropping right next to you when you just picked up a bomb yourself. 50% of the time when only 2 players are left alive one of them gets bombed out of nowhere without a chance to react. That's just not fun. Player controlled bombs should have a cooldown of 5 seconds after they spawn before they can explode and another 5 second cooldown after they exploded before the next one spawns. And there should be an option to disable them completely.

4. If a character is concealed by an object you should show the outline of the character. In a level like the kitchen sink you often can't see anything at all for example because your character isn't visible.

5. I'd like to have some slightly larger maps. Small maps are fun as well, but on some of them you can hardly move without getting blown up all the time. Which probably is the point, but having more larger maps would be fun as well.

EDIT: An explanation of the points system would also be nice, but I got it now. One point per kill, three points if you are the last man standing, minus one if you blow yourself up, minus two if you blow yourself up as the king and +2 if you kill the king.
