Interesting with the level ups and equipment upgrades, a lot of content in the "big feedback loop".
I think that a lot people might be put of by the lack of "game feel", like particles, big bullets and screen shake. And not play all the way, to experience the rest of the content. I don't think the game needs to be a super intense action game, but I think particles and exp pop ups would make a big of difference.
I also like the generating shield. Would be interesting if you could do other things with it, like running or rolling. Just to make some mix up in the movement.
I only tried the beginning, but it feels like theres a lot of content: levels and quests to experience!
There is a lot of content in the game already and I probably will try to add a little more graphically pleasing elements later on, but I wanted to make sure that there was enough content for people to enjoy before I really started working on the graphics.
I didn't really want to add any ways to move faster because I wanted you to spend points on upgrading your speed. I felt that if you could just sprint everywhere, you could just neglect the speed stat entirely.
Other than that, I do think I could add some more particles and things like that, and thanks for the feedback!!
