Hello! Thank you so much for the feedback and playing our game! The reason why we decided to submit it as an incomplete project was because that we wanted to add some more mechanics and balancing (as expected lol) but we didn't really have enough time to make the mechanics within the deadline.
Scattering hearts around the room is also a great idea, we definitely have to consider adding that. Like we've mentioned in the post, the game is getting a complete overhaul with a bunch of new and improved things so we really appreciate the feedback!
Thanks again for playing!
