Sadly, it wasn't :( I can't draw to save my life, haha T_T The only game of mine currently that features completely original sprites is Apartment No.9 because I was able to team up with artists for the jam.
For my other games, I'm forced to use sprites that I either created in generators I've bought or sets that I purchased on sale and edited.
The sprites in DD come from a Japanese artist called sasAIchi who has sold a couple of packs of sprite art online for use in games. I don't like to use them as they come though because I want to make them at least somewhat unique to my games, so what I did was heavily edit the colours using GIMP. The original versions of these sprites are blonde with blue eyes + clothing is white and blue, haha.
I'm glad you think so :3 I certainly pour all of my love into them, haha. It's a shame that I suck so badly at drawing because if I could draw, I'd be able to do so much more!
I'm very thankful for Manly playing a couple of my games :3 It makes a huuuuge difference because my social anxiety is too bad for me to use social media very often, so I'm a fairly unknown dev with no way of getting my stuff out there. If not for people like him showing indie games on streams, I'd stay an unknown dev forever, haha.
Thank you for the luck! I will certainly need it with everything I've got planned :D And all the best to you too! Thank you so much for all your kind words :3
