Pretty fun so far. Got to version 0.5.1. My main issue here is the Heroes mechanic has very weird (or wrong) values. The cheapest option is the highest value by far. 10xp for 4 heroes. Buying more expensive options gives you A LOT less heroes than the cheapest one. The 75000xp option only gets you 3000 heroes, but spending that same amount on the 10xp option would get you 30000. Literally 10x the value. Not sure if this was intentional or if some values got mixed up.
