Hey, thank you for the feedback! It always helps to hear people's perspectives to update the game!
The buttons showing percentage to buying is something I'll consider for a QoL update in the future for sure! However there are labels in the game currently that show the modifiers and costs for upgrades, it may not be as obvious as I thought. If you hover your mouse over the name of the upgrade and leave it there for a moment, it will bring up a tool tip with the modifier and cost for the next upgrade!
This is true for almost all the text in the UI. I have added small descriptions to help the player.
As for not knowing how many of an upgrade you have. I don't believe I have a clear indicator of this in the game right now so that is something I can look into adding too!
The opening of the game flashing with the 'heartbeat' was my first attempt into some kind of animation in a game, I need more practice in that area for sure xD I'll look into it more in the future!
I'm glad you noticed the control bar stopping there when you enter dialogue (At least in the beginning where it matters). That was a common issue I even ran into myself when testing but having to step away for a moment. Due to already being in a dialogue and the next one triggering, it would ignore the new dialogue and not apply the new unlocks. The best solution was to pause the control timer which controls most of the game's timing and pacing!
Thank you again for your feedback. I'm slowly working on new updates between work and life, so it's somewhat slow. But I'm doing what I can in my free time, so updates will may be a little slow but I assure you it's still being worked on!
