The game has a lot of potential. I like that it takes inspiration from games like Slay the Spire. There are a few things that in my opinion, should be enchanted. The game feels a bit clunky at times, maybe making the character move faster would make this go away. Also, no music, the sound of the footsteps is the only music we got, which starts to annoy you pretty fast. I'd definitely play more of this game if you keep working on it!
The arena is a bit glitchy I believe. First time the dude disappeared and had to restart Chrome. Next, after I could start, raiders were transported to the arena but monster didn't. And finally, restarting the game again, when I click to go to the arena, nothing showed up. I'm loving the game so far and looking forward for the updates. Keep on!
