teleportation power should do /checkpoint when you right click
furthermore, when you press the light key and you don't have a checkpoint, don't make it use up a goddamned teleport so you gotta wait a bajillion seconds
just make it fail with the message - 'right click to set a teleport point!'
flight and superspeed felt very similar - flight doesn't actually fly, it sort of hops, and the right click launch was not very satisfying. try using setRelativeVelocity, instead of whatever you're using now, so you can launch yourself into the air. try modifying siba's noclip mod into the light-key flight manuever. that'd be pretty snazzy, ESPECIALLY IF THERE WAS TREES AND stuff YOU CAN HIDE BEHIND (think great deku tree)
superspeed should probably not make you die when you run into a wall, or better yet, make more open areas so you can run the hell around. best currently is the dam. that's not enough.
i'm not sold on the water feature - most of the fighting and movement will undoubtedly happen around the edges, making the water feature a big fat blank space you can't go into tactically
may as well just have a hole there... or better yet, put some islands in the middle.
every single power needs to display how much time before you can use the light power again when you use the light power, when you try to use the light power when it's on a timeout (press r to teleport, then press r again - displays time. good. do that for all of them)
chance is a nifty power, but the crossbow turret i placed my first round on the server was still there two rounds later.
rounds felt like they might be too long, but i was playing without any actual fighting going on. that might be moot.
