I really like this game. It seems well put together and it has the potential to be a really good game. One major complaint I have is walking into a room I would sometimes walk straight into and enemy before I had time to see and react. Another is the dodge roll has no clear indication of when it's ready (as far as I could tell). It also feels like it has too much of a cooldown. If you look at games like enter the gungeon, it has a quick dodge roll that can be activated really quickly after another, but you're left vulnerable for a few frames after a dodge roll. One last thing is that the bullets move way too slow. Bullets need to be fast and responsive. Not so fast that you barely see it, but it needs to be fast enough to feel like your shot has weight to it.
Other than those few nitpicks, the game is really fun and I enjoyed it. And make sure to not take what I said to seriously, as it is just my opinion after all.
