Rated 5/5. While this is an "idle" game there is actually plenty to do. It is like an RPG game boiled down to fighting and looting. (Some might say the best parts!) The developer has been very active on the forum and has been updating based on bug reports.
Speaking of bugs, there appear to be a lot of bugs at higher levels, possibly related to numbers overflowing to the negatives. There've been a lot of complaints about this happening to gold already. This also happens with skills (experience), and I think it may also happen to legendary items. I have noticed that legendary items level very quickly but then stop leveling at around 33,300, and I wonder if they are having overflows in their XP counters. You can get them to be higher level than that by equipping something much higher level to increase your player level, but they don't seem to gain any more xp.
Shift + Spell shortcut seems to be broken since the 1.06 release. (MacOS X - Snow Leopard in Google Chrome). Would like to echo previous comments, this game is great, and would benefit form keyboard shortcuts for casting and placing towers. Ninja bosses rely too much on luck, it is frustrating to play a 40 or 50 wave level over and over hoping that you will freeze/fear the ninja boss on the first shot.
Could be fun but is too buggy right now - energy randomly goes to -30 or more even with simple laser canons. Cost and need for farms escalates too quickly.
