I complete ALL game and I can summarize:

Game is good I really enjoy to play
OCs is good, especially chess, Griselda and Necomancer

Graphics are also good BUT... I dant know why developers didnt draw all characters. Like "Pixels-pixels... HOLY MOLY! Anime girl!.. K thats was good... Pixels-pixels... OMG chess! In different style! Absolute peak!.. Pixels-pixels... Yo! High-bit pixel art!"
And one more: sometimes walls and structures 1x1, 2x1 and 2x2 became invisible on background while I was focused on rival and his attacks so thats really annoying

Gameplay: I cant say anything bad but I`ll be happy if guys add new weapons and more characters to play because sword becomes boring while u play like for 2 hours already

Difficult............. HOLY... Ahem... Well... Nothing really bad but its more like cry of heart...U play, complete every level (not 1st try but thats ok) and training skills... And after all of that... She appears... 2DGF... My god... SHE IS NOT RIGHT! HER ATTACKS ARE NOT RIGHT! WALLS ARE NOT RIGHT! THE PLACE IS NOT RIGHT! EVERYTHING IN THIS LEVEL IS NOT RIGHT!..
This is the hardest boss and I really dont know why... And this isnt my skill issue because after that I beat Moldy (5+- attempts) and Nekomancer (3 attempts)

Music and sounds: nothing bad but Im not a huge fan of it

Rate: I cant rate this because the game isnt finished but for now this game is 6/10
