Hopefully not to big a spoiler clues for Hansul, for a silver 94 use the 2 hit to seperate the 4 reds. For 98, push the unblocked ones around with your arrows and line them up with the middle ones for multi hits.
For the dwarves on 17, humans are your first target. Head to the gem mine at top left and keep attacking then retreating from the wasteground above their castle. On retreat build up just enough forces at your stronghold to hold the orcs, the rest to attack. Once you take the east, use gargoyles to crush the orcs.
Looking good, better balance, now it's too hard early though. The screen shaking is annoying - if the menus/scores didn't shake it would help. Can't wait for the full version.
Sniper tower and flamethrower are overpowered, electricity is underpowered, lots of glitches and bugs but nothing majorly wrong. Using boost towers instead of upgrades is nice. Needs a ROF bonus tower though. Also needs selling or demolishing and bosses. It's looking great, can't wait for the finished version.
Interesting puzzle game, good concept with nice graphics and great sound. Perhaps make the first 7 rows visible and the rest stacked instead of only being able to see 3 ahead in later levels.
