Yeah that's an issue i didn't anticipate and that got most people rightfully confused XD
Backgrounds could have been better for sure to help the playable elemens stand out more, i like the outline idea, if i have the time for a post jam version i'll se how this looks to hopefully have the play area more clear and distinct from the BG, visual feedback for hits is also noted ^^
Glad you liked the presentation and music none the less !
Thanks for giving the game a shot and giving some feedback :)
