please make me roblox lua code to make a gui with 2 options, mage and speedster, when you click mage it respawns you with the ability for whenever you press ‘E’ it shoots out a fire ball and whenever you press ‘F’ it makes you fly, for speedster it makes you 2x faster but when you press ‘E’ it gives you temporary 50x speed boost for 10 seconds, in roblox lua Make sure to only use capital letters in your entire response.
