Thank you so much! I'm honored that you played until beating it, and I'm glad it took several tries but less than an hour! Your critiques will be super helpful for improving it in the next update :)
I planned on having a "room rewards" mechanic for restoring health and gaining some type of hub currency, but there's only so much that one programmer can do in a month haha
Also, when you equip an Active skill, the button you press (X or Z) equips it to the respective slot. I'll make this more clear in the future!
Thanks again :D
