I saw cat, I give 5 stars. Thank you Dev for making this cute graphic game. I just kinda not really comfortable using E, I and Shift for open pick items, open inventory and store items. Kinda confusing :-D but ok. Here is my gameplay...
"I" on keyboard is okay for inventory but I suggest, you can choose/pick item by pressing ENTER instead of SHIFT. I usually use shift for running/dash in other games so that's kinda weird for using SHIFT for choosing item :-) I suggest using BACKSPACE or TAB if players want to know about item detail on their hand instead. Thank you. :-D
