After collecting all of them gems in the game and finishing it i feel as though i'm ready to give my review.
Gameplay: The black hole mechanic is very fun to mess around with and you have to learn how to use it properly if want to beat the game and even more so if you want to get all the gems. At first it seems a bit odd to get it to do what you wan't. But once you learn that each side will give you a guaranteed result it becomes a joy to experiment with. However I still have some complaints with the gameplay. One, the camera killed me a little too much then i would like, as sometimes as i was being thrown to my next black hole and lining up which side i wanted to hit, my mouse hand hand't been following my character thus the camera wasn't. Might i suggest i move camera function, something that you bind to a key. So when i hold shift or something then the camera moves and if it isn't held it follows my character. Two the black hole mechanic can be cheesed. Need more black holes just mash c! You should disable the reset when the character is in mid flight.
Graphics: I like the graphics, there weird and fun and the cat is chonk. Though the levels aren't heavily inspired the choice of color and tile set make the game stand out in a very good way.
Audio: The audio is also done very well, though i do have a complaint. Its not the fact that the music is composed poorly, its just the fact that it feels like it doesn't fit the mood. You want something to jaunt you along while exploring this odd world as this cute cat. It feels like the audio composition is good nothing special but the theme needs to be worked on here. Other then that the sound effects on the pottery, black hole and everything in between were good and felt liked they belonged.
Theme/conclusion: All and all the game was very fun i think you did a very good job. Everything comes together to give a great sense of originality, great themes and fun gameplay. Advice for future updates to this or next project, just think about the simple exploits and quality of life aspects. The camera mechanics need to be thought about more and the mechanics with the black should not be allowed to be cheesed.
