1-) Mechanical
mechanically not bad but there are these issues
1-) it requires reflex but at least we have a time slower
2-) 2 obstacles can come at the same time and this bug could be fixed
2-) Design
the assets in the game are not bad, but the use of a pixelart ship and a 2d cat surprised me
3-) Presentation (describing the game)
The presentation in the game is not bad, but a little difficult to understand
4-)Theme
You used the theme in the game a little differently and it surprised me
In short, your design is quite different.
My rating: 3-4 (at least you won't be last out of 5)
Good luck with the jam :)
