I played dome keeper a bunch so I'll do a lot of comparisons, I guess. (and abbreviate it DK)
At first I didn't like the attractor beam, but after upgrading width I started to like it. It's really prone to resources getting stuck on blocks that half obstruct the way. It's also worse than DK in the way that you have to commit to a single direction. DK's elevator feels amazingly useful from the first moment, a must use in all runs, unless you find a teleporter first. even then.
The map generation feels kinda bad. I got hardblocked very close to spawn in two directions.
It's possible to bounce back and forth between blocks even if you don't intend to but it feels like a bug to speed-mine this way, not like skill expression like in DK.
The win screen opened behind the upgrade screen but I was able to interact with it.
You might want to have a toggle for the gun to rotate towards the mouse, if M1 will be used to shoot the gun.
There are other DK input parity things that are missing, I think using Q to quit the upgrades is one. not sure.
I can't say I enjoyed the glass around "relics" having collision. it's bothersome.
It was difficult for me to distinguish "water" blocks as resource blocks before I interacted with them, I think in DK the earth blocks have a more neutral less noisy texture to them which makes you recognize the special blocks right away.
It has a while to go before it's not "DK but worse", but I think you'll get there.
