1st lvl: what a stupid "game"
3rd lvl: FREAKING AWESOME
Conclusion: don´t judge a game by its 1st lvl.
Hit boxes are actually good. Many games have issues with rotating references frames, but you did a great use of that and turn it into a nice core mechanic.
Simple and nice. to "favs" it goes.
PS: my vision keep twisting by a minute LOL.
