Going to repost dauntless' comment as I think it might have got buried. but he makes a great point!
RE: autocasting at max mana. While it may not take "extra time" if there is mana left over, if I manually cast something that takes my mana to 0, the mana still has to get to 100% before it will autocast. Why doesn't it instead just autocast at the minimum amount of mana to autocast the spells selected? It's a small quibble for me because it's less efficient, but I see no reason why the trigger is the mana reaching 100% instead of the amount needed to cast the autocast spells.
In response to the dev, I think it'd be cool if the 2 blocks had some interaction, rather than the small block just being for aesthetics. Balancing is also an issue, as I currently get $172.9b per block kill, but earn $5005 per bar that I fill up. Other than these small niggles I have, it's actually quite a fun game to play!
I previously coded the game so you actually fought the opposing block, but doing several clicks which resulted in an eventual loss made the game much less enjoyable. Is there any other way the two blocks could interact without actual fighting? I'll go ahead and increase the amount of money you get at the later stages of the game through upgrades (Should be done in ~15 minutes).
Edit:
I slightly decreased the initial amount you get from rewards and increased the amount you get from the bar. Hopefully this helps even it out a little bit (Although it will still become unbalanced at later blocks)
Kinda confusing to work out what each upgrade does. Feel that a little more time could have been put into this game and the result would have been much better. 3/5
Aside from being confused about what each upgrade does, what else would you suggest changing to improve the game? I'm considering adding a tutorial to help people understand the basics at the start.
A bug I believe: level 6 ovens use 10 snails, but only produce 1 burger? (Is this a bug at all?), I presume you meant them to cook two at once, hence the two cookers.
And also, target range is waaaaaaaaay too hard as a mini-game. Impossible to get a combo.
This game is a really good game.
But it only has an easy and a medium achievement.
Perhaps add:
Hard - Complete game on Harder.
Impossible - Complete game on Impossible.

The specials have different chances of being caught, Orb 3 is a bit lower.
