Some feedback:
so, I've really enjoyed this game, it's a bit difficult, but that makes it even more interesting! I think the monsters and bosses are really creative, and I love how all monsters have their own, unique playstyle! Also, I love how you're able to choose your team and use "food" on them, according to your own, personal style. Personally, I'll use a "Technical", and a "Defensive" monster at first, and evolve both of them before Zone 2, then get some eggs, and have a team of maybe 3-4 monsters, atleast one of them being maxed.
I think the combination Gheist + Strigeye is extremely good, and I try to get this combination in almost all runs.
Zone 1 boss is usually easy, I defeat him most of the time, Zone 2 boss is a bit harder, but if you have atleast 1 defensive monster, he's not that hard. Zone 3 boss is extremely hard, and I could only beat him once, with 2 monsters maxed.
In my first runs, I tried going only one type of monster, failing miserably with aggresive, and getting to Zone 2 using defensive.
All in all, really great game, there *are* bugs, but none of those that I experienced were game breaking, mostly some small, annoying visual bugs, and I will keep reporting when I find some.
Great game, great replayability!
