Game is very fun, but also very grindy. Would like to automate events (maybe after 5-10 second timer or toggle defaults from a menu, maybe unlock this after first prestige? Even just a simple skip event toggle would work too). Automating runs would be great too (I love overnighting idle/incremental games).
Damage upgrade does not scale well, especially noticeable on higher waves (+10% more damage multiplier instead of +1 damage would be nice). Knockback on cannons is overpowered, especially on bosses. Pushing to more than 6 prestige points on the first run is very hard with the wrong setup. Might be an end-game balance issue. I soft locked on wave 41 and ended up in a stale-mate because of the wrong setup (pretty much all crowd control and not enough damage). Sell hero button would be great for a partial refund incase I want to change my setup during a long run.
Priority targeting would be great (i.e. close, high hp, low hp, etc.). Better automated upgrades would be nice (it seems to dump all my gold into the top hero and mostly ignore the other ones. It also seems to spend most gold on damage even though speed is a top priority).
