The portals confused me at first, but when I understood them they seem like a great idea!
Really liked it, well done!

Great take on the limitation, I liked even the way the menu is displayed. The game is fun to play, the smash turbo makes a great contrast with the slow regular speed, making you take risks (as to collide with a not-so-open portal).

As a constructive critic, I would add some spacy soundtrack, playing as a background. And I had some trouble finding the green window-of-oportunity of the portals, maybe it could be less narrow, or more clearly displayed?

In summary, very good work :)

Nice game! I really liked "SMASHING" through the space ahhahah

But I agree with Bunnywabbit13, the movement at some points is reaaaaally slow haha

The WASD feel kinda weird, it's very slow.

a classic retro-style asteroid game, can't go wrong with that one :D

the horizontal and vertical movement could be a tad faster, as it's painfully slow to try to hit those portals :p
