Thanks for playing! There are some serious balance issues so it's common to not be able to pass more waves honestly.... The jittering is something that is driving me a bit crazy as I'm not able to notice it, so it's either a bug or I should just give up on life! The fixed camera over the whole arena is not really an option due to the size, if I were to change the proportions the player would be too small. However, the minimap you are talking about is a great idea that didn't even cross my mind for a second, I will definitely implement it in a later version. Thanks for taking the time to even read the description and for the feedback!
