Overall a good game. The only issue I see is the fact that many chests are often hidden behind a wall of items, and, in one case, a quest item was behind two walls of items. This can be very annoying at times.
This is a good and addicting game. The problem is that if you want to do well, you need to be willing to pay, and that just ruins it. 1/5 stars for making a good game terrible by charging at every turning point in the game and making it too hard to do well without them.
Pros: Excellent game. Plenty of upgrades while no weapon is really a complete "beat all." Each weapon tailors to an person's specialties. Exp reduction to prevent people from trying to get tons of money and exp early on is an excellent addition. This game will keep you playing for hours trying to beat all of the levels, not including the challenges.
Cons: Game can lag very easily on slower computers. This makes it significantly easier to win the 25th and 26th levels. Also, 26th level can be easily beat if I player enters with one golden gun, and when they are 20+ levels below 60. Player can easily keep recovering health every few kills due to the leveling up.
Considerations: Assistants and helpers. Notifying the player that they will not be able to buy all of the upgrades early on, rather than letting them figure that out around level 15 or so. Otherwise, great game. Loved it. 5/5 stars.
Also, when am I able to mark my map? I've seen higher ranked player's maps that show where planets and black/white/worm holes are. When can I mark those?
