ofc he is trying to improve his work, if u saw 'the horde' which was the original he based this off he has come a long way, just need to balance the upgrades really as 10 damadge on a lvl 0 arrow tower is a massive upgrade but 10 damadge on a snipe is pritty crap, simply make is a 10% upgrade isntead of a flat 10 may solve this.
a good game a little spoiled by the fact once u can build a secondary fortress u can then use artillery from that to actualy damadge the main base of the reds
gemcraft feels beter in sonny in many different ways like for one variety, 7 diferent 'maps' on sony like a hundred on gemcraft?
unlockable content on gemcraft, heroic completed giving new levels, remards for repeating levels in more than exp terms which is all sonny offers, but stil i like sony and i like both so i gave both 4/5. why do people feel the need to chose between when u can have both.
remember u need to kil the little ones first on arcane guardian levels so the guardian doesn't walk strait through with insane armour and get to your tower, generaly a good idea to ahev stoped building anything new 3ish levels before the last so u have enough mana to banish the guardian once.
remember u can gem bomb a line in your inventory to change it to that color if u geting bad gems when u create u lose the one u bomb ofc but u get u to 3 of the color you wanted :)
