The only achievement I might see people not getting eventually is "The Leveller" which requires you to level each fish at least once, since you're not actually required to click the fish; achievements double your income so it'll affect your finish time significantly.
Another achievement is also clicking the fish (any is fine, they're accumulated clicks overall) a total of 777 times;
You should always buy the highest level fish you can, fish income increase in purchase intervals of 5.
The last part when you got all the security codes to save everyone felt amazing. To replay all those levels where now you could do what you couldn't before is just a great feeling.
I beat the game using the Rouge, Dark Cleric and the Air Wizard.
The Rouge serves as your AoE clear and also main boss damage which is a support member. You only need to max Throwing Mastery for this to be most effective since you won't be using him as a team leader.
The Dark Cleric is your source of healing over time, an aid to recharging your super bar, but most importantly the ability to revive a fallen party member. For the Dark Cleric to be most effective, Regeneration, Bloodlust, and Resurrection should be maxed.
The Air Wizard, also your Team Leader, serves as a barrier which deflects all projectiles (besides lasers and melee enemies) and also does AoE damage around your party. For the Air Wizard to be most effective, Haste and Tornado should be maxed for utility and protection.
Tip: The differences between each item tier is the amount of stat line bonuses they have and the amount of stats that it is increased by when it is upgraded. Meaning a magic item will always 1 line of bonus while an epic item will always have 4 lines of bonus. When you upgrade the epic item, it will gain more stats per upgrade than if you were to upgrade the magic item.
Well, Game's kinda short since there's only 17 Raids.
For a tip, Having 1 big hit in the beginning and then 6 bonuses after it will be sufficient for winning the game. You just need to keep building the drums in correct areas. Emphasize building drums around the middle where the drums can hit several enemies at once, so don't build any drums near the huts unless it's the very beginning of the game.
Once you've been able to free a shamen, I recommend putting the 6 bonuses first then the last big hit for the elephant drum, and place it in the middle where it can upgrade all the drums. The elephant drum is pretty useful in my opinion, even if it takes up 4 squares.
I like this game alot more then Crush the Castle, The aimming for Crush the Castle is much more the "Predicting" factor while here you can click where you wish to attack. The Physics are also better in my opinion with the blocks being able to break.
Adding more "Hobo - Like" activities would be a nice addition. Drinking isn't really something Hobos do since they can't afford that many beers :P Maybe going through the trash, Or something like that. It's pretty nice until you run out of things to buy & upgrade though.
Tip : If you cut a tentacle at the beginning (Near your cell) all the remaining *Tentacles* will go towards the cell that you were extracting to. If you cut a tentacle at the end (Near the enemy cell) all the *Tentacles* will go back to your cell. If you cut a tentacle in the middle (Half way between your cell and the enemy cell) half of the *Tentacles* will go to your cell and the other half will go to the enemy cell (To attack)
For E8 (Don't Be Too Hasty) You don't even need the cog or ball to get the other cog. Just get a 2 Inch Block and drop it in the hole at the top. It'll hit the cog allowing you to get it through the other hole.
