This game has a lot of potential. I think that there are a lot of bugs that need to be worked out as well.
I've noticed that if you redistribute your points when you're maxed out in levels and have extra exp your level will sometimes go above your max I.E 100/99. This does not count for rebirth level 100 but is visual and can be a little confusing.
I also think that having to choose between a rebirth or ascension is a little frustrating. If I've left it on over night I'd like to get those ascension points and not have to push to 100 again. Rebirth should still give you the "After ascension" points in my opinion.
Like a lot of people have mentioned there is a lot of spelling errors, this doesn't bug me as much since it's brand new but working to fix this would be a goal.
The last thing would be the lack of information. No idea about how to get to Tier 2 unless I read the comments. The amulet unlocking via stage but being blank till you buy the ascension was confusing.
Keep up the good work though! Excited to keep playing and see where it goes.
