Honestly, for the difficulty I didn't expect it, me and my tester find the game quite easy, I will try to put myself in the player's shoes as best as I can in the future! For the drop, I notice now that it's more annoying to change level every time, but I really wanted to have the fact that the player when he plays says "ah too bad I didn't get this kitten, I hope to get the next one!"
Anyway, if you liked the game, that's the main thing !
