Thank you so much!! :D I'm really glad you like it!!
And yiss, Undertale was definitely an inspiration for the art! I'm glad you saw that! And yeah, you're right, I wish I could've added more to it, I had so little time (I always start working on jam projects very late for some reason). I'm definitely gonna add some increased difficulty and ways to progress when I update this, though, eventually!
And you're right! A few people have mentioned that too, I'm definitely gonna add a time limit/cooldown to the time-slowing mechanic when I update this! Thanks a lot for the feedback, it helps a lot! :D
