This initiative sounds good, indeed it is frustrating and slow when moving on to the next group of 5 levels and this idea will help...
Personally I will not benefit much from it since i am already lvl 40, but maybe one day you will give us 15 more levels
I would suggest you consider these changes too...
1. Slightly increase the item drop rates - the number of items required at the highest levels is huge, making progress very slow... try looking for 60 Fabric Filters for example to see what i mean... so please consider increasing the drop rates of the Uncommon and Rare items, not by much, just a little
2. Increase the selling value of the items such as claws, bones, meat etc... to upgrade the highest levels you need to spend like $28,000 ... so please, at $9 a piece these items are less than a drop in the ocean
3. Increase game speed... please... enough with the slow down when hit! games in this day and age are fast... we love them fast... sure it is a good idea to make it slow?
and i play with Coelo, specifically because he is meant for speed... the slow down while hunting for me is the number one most frustrating thing in the game ... so please, enough of it, i am begging you!
