Hey! ;D My name is Guillherme and im a brazilian java programmer(sorry for any typo) and this is the project im working on for the past 3-4 months, thats my first “big” project.
Wave Defender(not final name) is a 2D stage rpg type game, alot like Binding of Isaac that runs in my own engine using basically java2D and slick for sound, so performance can be a problem with the lighting system 
My bigest difficulty is the game art, 70% of sprites are placeholders and you may recognize some of than xP. It would be awsome if someone helped me but im playing around with photoshop and doing some sprites myself.
