well, took me 2 rebirths before I could till level 50.
I could likely play way further but currently, with tons of maxed out ballistas and all sorts of other maxe dout weapons, nothing really makes it really far into my base anymore.
even th 5 bosses at level 48 couldnt even make it till the first bend in the path, the yslowly but surely died within the first 5 meters after leaving the portal.
dont see much reason to play any further, enemies arent an issue anymore, i got like 400k and more of unused money lying around.
and it's already more of a slideshow with like 1-5 frames per second, for the msot part always 3 frames followed by short lag.
was a nice game for thre time it lasted :-)
Thanks for the feedback! I am currently working on a tower leveling system that'll make money much more useful endgame (every level will double the price of upgrades). With this system I will hopefully be able to get away with a much higher difficulty curve so the game was properly playable longer. (Performance update is not promised but I'll try to do that too)
