found a little trick when selling items in the store.
-Left click to start the transfer of items and then right click once. It will bring up the flash options box but your item transfer will continue under it. At least you don't have to break your finger when transfering large volume of products
For those asking about the key controls, you can use WASD (look in the options). My big problem with this game is the fact that the level loads stick sometimes. If i hit a direct replay of a mission, it sticks at 100%... level 9 also sticks at 100% on the first time I try it so I can't even play it.
@ IchigoKurosaki1, I always kept a set of 'magic items' onhand and never sold them incase I had to use the Wings. This lets you re-equip each slot with some decent gear each time you restart. Another tip to try is to use your wings a few times before moving on to the merchant level. You keep your gold after using wings but just loose your non-magic gear. It wasn't until I reached maybe level 60 before I stopped doing that. At that stage I had around 20k gold and just bought out the flasks at each merchant. Another bonus to doing that is your stats roll over with you after using the wings so you can grind a bit to raise your stats as well.
Like many have already stated, the colours are hard to see against the brown background. Either change the colour of the puzzle background to white or some other contrasting colour. Nice game otherwise
2 lasers and an upgraded minigun per elevator is all you need. Just jump around to the floor with the most critters.
I finished with 2x lvl 2 laser and a lvl 3 minigun on each floor and I could have just sat back and watched. None reached more than 1/4 of the way across the floor
Nice game, reminds me of the game Bridge Builder or Pontifex.
Only complaint I have is in the design phase of the game. Would it be possible to make graduations or graph paper like marks so that it's a little easier to align your pieces and maximise your designs.
