**Edit 2 - Wiped all progress when I was allowed back in and no way to sync with old account. **Edit - No longer playable. Telling me ive played on a newer version and to download the newer version. tried to uninstall and reinstall and still not working. Pretty good. basic, but not riddled with ads and don't feel like it's just a money grab yet

Really fun and addicting! The core gameplay loop is perfect as is with the energy system and tower slots. The only improvements I'd like to see are the option to merge duplicate cards as part of some sort of prestige system, as well as the option to save multiple decks as presets. I'm really excited to see if any new towers will be added as well as higher rarities and what that would look like! Keep up the good work!

I only got to level 23 because it was getting increasingly difficult to pass the actual levels. You don't get new cards that can help unless you either spend gems, which can either be bought with real money or obtained when you beat a level. Most of the time you don't get rhe cards you actually need nor do you get coins to level up the cards, but most can only go up to level 10 if you don't obtain the materials needed, which can usually be obtained by the daily "challenges"
