I found it very polished, from particular main menu but also the gameplay and everything was easy and clear to understand. For me personally, it just got a bit repetitive toward the end (more interesting enemies or something else to keep you engaged would be cool, i guess💭)
One small thing: in the pause menu, the button said “start,” and I was afraid to press it because I thought the game might restart.👀
Overall I had fun playing it :D
