Kind of both, the entire game just gives the vibe of 'sluggish', turning is slow, moving to your chosen area is slow, bullets are slow (particularly made the small enemies a pain in the arse) - but also at the same time, yes farming resources are slow, collection bots don't feel they do so much, there is a lot of waiting around and almost idle time trying to farm up - it is all a slow process from beginning to end, and taking 6 or 7 minutes to fly around in a circle and get about 3 upgrades worth of material hammers that home even more
Even the upgrades you do get seemingly have minimal effect (I know it's a small demo but this still applies) - tiny amounts of engine power or bullet speed or even range - expecting maybe a 50% range boost and getting less than a 6th, meaning even more materials for a not so great reward
I do like the unique patterns you have to fly in to try and defeat some of the enemies, but it's just a symptom of a system that isn't fulfilling it's purpose
Damage was about the only thing that felt like it was in a good place right now (with 5 cannon ships- can certainly imagine it too would be painful with an accelerator or healer.. again extending the resource issue from killing slower)
Anyway, i'll stop rambling, it was an okay experience, it does certainly need work, but I wish you well with continued development and hope you're able to refine the product in all the ways you want to
