Hi Madson,
Thank you for the feedback !
Input and basic gameplay should be improved in the major update I just released. To avoid interfering with the MGGJ8 submissions, I created a new entry 2 weeks ago. You can find it here, named Touch 'n Ghosts : https://arcade-eleven.itch.io/touch-n-ghosts
Currently, the game is still a bit repetitive, but offers a clearer objective with a record to break. A major game mechanic is still missing, and should be included in the next update. Together with levels and story, the game should gain some depth. (or at least, I hope so :D)
Hope you'll enjoy it !
