I really enjoyed your game! The intro was amusing and thematic feeling, it set up the game well! The movement of the ship "stuck" at points (right after picking up shards I found I couldn't rotate the ship unless I move forward first). I like that the ship is slower when it is weighted down, but the use of the boost (with a cost of energy) is a great way to give you additional options. I wish there was either a mini map to assist with orientation (I got lost a lot trying to get back to the hubs/shard bank) or a way to plop down a flag or some kind of marker that your ship would then have an arrow pointing towards. I feel like that might be a good way to allow lots of exploration but still give the play some kind of way to navigate back to places they've been. Perhaps you start with one flag and you can buy other colored flags as upgrades later on? I would find it useful to flag the hub and if I found a bunch of crystals I want to return to for instance. Overall though I really enjoyed the game and I hope you continue to develop it! It has a lot of strong points and I think you could build a lot more into it!
