Love the game!
I did run into a bug where a door wouldn't open, not sure what happened though.
Except than that, I felt like it was really hard to dodge the bullet, I couldn't really keep track of all of them by using my peripheral vision. Maybe adding some highlight or something similar could help? Have a fixed location for the main character, like maybe on near the mouse as a target, could really help keeping track of the current age without having to always look at the player.
Anyway, still enjoyed the game! Could be a good mechanic for the next Enter the Gungeon ;)
