It's my first time playing this so you've probably heard these before but here's a little list of things I'm writing down as I play.
Starting cut scene is way too long. I was on board for about 2 minutes but after that I just kept mashing to skip everything. and I was astonished as to how much mashing I had to do. Sad part is, I Was enjoying the dialogue. I'm sure you're planning on having a proper animated intro at some point but right now staring at a wall it's very boring. If I were you, I'd try to space out your initial information dump in between gameplay. This would hold true even with a proper cutscene. Players are excited to play your game when they start. don't let them down.
UI is very overwhelming at first. it might be good to outright hide all the options that aren't available yet. Gradually introducing them in as you unlock them.
Little weird how you have to right click to get information tooltips. it feels more natural to me that they're just always there when hovering.
There's a bug (on linux) that if I minimize the game on a loading screen, my mouse will disapear and I can't click the button to start the dungeon. however there's a workaround where when the pause menu is open in the loading screen, you can click play from within the pause menu. unpausing the game still keeps you in that state of not being able to click play.
(This room is not fun)
The game is fun, honestly. It's hard but it's a game you can see yourself becoming good at (which I'm sure you are). The thing I HATE, is the time limit. I feel like it's completely anti-fun. Or at least, the fact that it kicks you out of the dungeon. It's not very conductive to you getting good at the game. I feel like the game could be a lot more approachable if the time limit was reworked in some way. Either extending it by a lot or making it a requirement for greater rewards without ending your run altogether. Maybe even implement a rating system to see how fast you cleared a level and base rewards on your ranking. But ending the level when the timer hits 0. not fun.
