Hi! Just played it for a bit, nice work!
What I liked:
- The atmosphere and the art are really pleasant
- Running straight in the browser is great, no download, I could start right away
What could be better:
- When the game starts, I didn't know what to do. A small tutorial or a little help window on the first launch would really help new players get into it.
- When I want to buy something, I can't see how much money I have. Showing it near the shop (or next to the prices) would make the buying decisions much easier.
- To buy, I have to click a tiny icon. It would feel much nicer if the whole card was clickable.
- After buying an upgrade, I didn't realise it had increased my damage, or that I still had to keep clicking. I thought it would attack for me. A short message after the purchase (like "+2 damage per click") would make it clear what changed and what to do next.
Good luck with it, I'll keep an eye on the updates!
