I like the meta progression and ship building concept, but it's a bit grindy to get upgrades and (as far as I can tell) the game doesn't save progress. I had to repeat the first couple missions repeatedly, due to dying, and I think they are a bit tedious/boring without a gun or way to interact with enemies and iron chunks. After getting a nice setup with 3 rifles, 1 shotgun, and 2 guns I ended up dying instantly to colliding with an ice chunk, this didn't feel intuitive since colliding with iron chunks didn't seem to cause any damage to my ship. I gave up before getting to the first boss.
Thanks for playing, I didn't manage to add a save system to the game, but I did plan to. I could shorten the first few levels into one level to make traversal a bit easier, but my thought was to split them up to allow the dialogue to be more digestible. Both ice and radium chunks do hurt the player, though I should have communicated that better with a colored circle.
