Thank you so much for all your amazing and detailed feedback!
Indeed, I did want it to only have forward thrusters similar to the original asteroids game, and you're making a very good point in terms of playability.
Multi-directional thrusters sound like a great idea! So I'll be sure to better next time and create something with better playability and directional steering.
For the deaths, it's a bit of a puzzle, so I apologize if it was too cryptic, I'll do better next time to include a tutorial or better instructions.
In this case, the blue cubes are meant to contain pure energy that when merged with your ship temporarily deconstruct it and remove it from this reality, which technically results in you being killed in the process ... BUT due to the hyper charge of all the atoms around your ship, all the parts are instantly pulled together again and reconstructed by the intense energy.
I'm super thankful for your detailed feedback and really appreciate it!
I promise I'll use it to create better designed games in future! :D
