Hello! Thank you for your feedback that's awesome!
I can't add variety to the characters cause it's all hand-drawn and to add one option I would need to redraw aaaaaall the sprites! On the other side I'd love to add one or even two new species and their skilltrees to add new flavors to the game! The tigers and the rats!
Thank you again for playing the game and I'm super happy you enjoyed this game!!! X)
