Developing this game would have not been possible without the aid and support of the 'Lazy Devs Academy' Community. Helping me with anything I asked, and encouraging me to move forward, notably, 'Aktane', 'otto_piramuthu', 'LouieChapm' and 'SquidLight'. Through their own strengths they have helped me reach to where now this game exist. My gratitude goes to them. A very special thanks to 'Krystman' for fostering such an invigorating community of creators, teachers and learners.
And as always, my unending thanks to epicheezeness, for all your support, attention and direct contributions.
