conceptually this game is a clone of this is the only level but without elephants, i don't have a problem with that and i think it should take some lessons on why the elephant game is so good.
-for starters every time you fail the stage there's a loading screen that feels really long after it repeats a few times, it gets annoying when failing the levels multiple times.
-some gui elements should be removed, it has a setting for the music volume but there's no music aside from the level complete jingle and the close button makes sense on desktop but here it just crashes the game, forcing you to refresh the tab, it gets really annoying when you accidentally press it accidentally.
-speaking of the close button, it also crashes on the pause screen, it should act as a main menu button instead.
-the hints are either give away the solution or are not helpful at all, there's no middle ground, in my opinion it would be better if there where no hints at all and instead the levels had names that doubled as a hint (i.e, "level 1: button opens door", "level 2: the opposite day", etc), that way the player isn't forced to open them all the time as some levels can't be completed without them.
-i don't know if this is a bug on my side or not, from the screenshots the game looked rather small but when i played it, it loaded at a huge resolution and the game was letter-boxed in the middle with some of the spikes cropped
-level 11 seems to be borked, specially when you move while the game is paused, sometimes it will kick you out to the main menu, sometimes it will crash.
i think it could be a good game but it feels really rough around the edges and it's very prone to crash, i gave up after reloading the page 15 times because it crashed so often.
