hi!
thanks so much for your feedback and saying that you like the visual style!
you are totally right when you say that the levels aren't very clear and it is something that i will have to fix.
when i was making this game i was trying to not use any UI at all, mainly because i enjoyed a very minimalist look (the lack of UI and just seeing the physical level on the screen etc), so i ended up using 3D signs in the levels to teach players the mechanics. what i didn't think of, was of telling them what to do because the levels are quite short and i thought i'd just let the players explore! that being said, i should definitely implement some sort of "help! i don't know what to do!" button or something to help players.
and the reason for the discarded levels is that this was a university project (it is my first game that i've ever made!) and so i had to stick to a deadline and didn't have enough time to design or polish the mechanics of those levels.
anyways, i'll keep your feedback in mind! thanks for commenting! :)
