Thanks a ton for the detailed feedback and the kind words. It really means a lot.
You pointed out some really important balance issues and I agree with most of what you said the "Parrot strategy" (first strategy on the game yay !) and energy carryover clearly break the game right now (even if energy keeping between fights is intentional).
I also totally see your point about low cost cards being useless the lack of punishment for deck size and the repetitive gameplay loop. These are things I plan to address soon especially by adding more meaningful choices during runs and mechanics that force the player to adapt instead of repeating the same setup every time. I like the idea of a side deck or maybe a more dynamic hand system too. Definitely going to explore that...
And yes this demo is super basic for now but I am really glad you found it fun despite all the rough edges. I appreciate you believing in the project and I am taking all your suggestions seriously.
Thanks again and feel free to share more thoughts anytime, it really helps a lot!!
