Hey, not to worry... maybe to make the process of shooting easier on the second level with the charges, instead of right-clicking to increase the charges one at a time, maybe holding down the right mouse button instead increases the charge value over time? Just a suggestion, but don't be too hard on yourself, its a learning experience :) and you will surely be able to build on top of this if you do proceed with updating it or taking what you've learnt to your next project...
