Uhmm have you tried to use the function "RepeatEveryXSeconds"? It helps me a lot with the performance of PathFinding objects. Use it to move the enemies towards the character, but instead of all the time, every 0.2 seconds more or less. The player won't really notice the difference.
Awsome! The idea is similar to my game lol, I really love the art, as an advice maybe you can create more enemies more stronger or faster maybe, because after wave 7 my laptop wanted to cry lmao there was some lag, that's why instead of many little enemies some stronger would be nice. Also can you tell me how you make two enemies not overlap? Because I tried I did not succeed. Really nice work!
I got 7600 points, but how can I use the mony that I earn in the destroying ships? because i wanted to buy others guns, anyways it was very fun. Nice work!
Very innovative and fun, but there is a bug, if you put a block in front of the tank then it is not going to move, but the points do. like in this image:
