The hard controls make this game more addictive honestly!
I have died so many times, but I keep wanting to play it. If I die at the sage part I ll just restart the game in order to have my 7 hearts for the next level. Gives me the flappyBird/unfair Mario vibe. Love the fact that there are different soundtracks. Honestly, keep the controls as they are and I know you mentioned you will add checkpoints. Character customization for the Ghoul ? :))
loved it
