… For starters, it would be nice if the playing-field came in different sizes/layouts, specifically taller so more complicated paths could be built. But smaller, non-rectangular etc. and/or other playing-field “mods” (I dunno, teleports perhaps, or branches, either randomly chosen or filtered by mob-type, etc. etc. - Be creative..!) Another, minor, issue, is that it is sometimes very hard to get going, if the first set of random-draws are particularly “unfavorable “ (ie. you get towers that are sub-optimal initially, such as non-dmg. towers / towers dependent on others or on certain upgrades before being powerful enough to matter or such “bad combos”). Wouldn’t be so much of a problem, if this didn’t happen so relatively frequently as it does. My best attempt at a possible solution / improvement, would be to choose between one or more pre-defined lists, each containing a hand-picked sub-set of towers and upgrades etc. that are known to mostly, if not always, produce a viable combo of starting towers/powerups/etc. when the random selections are all made from one such list. This would only need to be done for the first one or few levels, after which it will be much easier to survive one or more levels where the random selections are bad / sub-optimal, as one already have some towers up,and running etc. Hope this helps, keep up the good work devs ;)
