The sprite-work reminds me of Guilty Gear, the movement reminds me of Nightshade and Shinobi, the combat reminds me of ICEY and the soundtrack (especially for the first boss) reminds me of KOF2K2UM. Your performance is great, it's like seeing a 2D PS2 Shinobi in execution. I hope to get it one day. This is so well animated it makes the No Damage look like an anime episode. Pretty cool parrying at 2:38 as well. I can tell this is very challenging. Looking forward to the next part!
