Cool game!
- Innovation – The turning cannon pushing thing is a unique idea.
- Fun – I like how things wrap around the screen to the other side.
- Graphics – Clean and simple. Since you're using Unity you should add some more particles, screen shake, post processing, etc. to make it feel more premium~
- Audio – Simple and cool!
- Polish – Just needs more game feel / game juice
Great job on the game idea! Please check out my game if you like Metroidvanias or platformers :D
