Pretty nice game you got here. I'm very much a fan of early Pokemon game design and it seems that you have captured the aesthetic pretty nicely. Even though it still needs quite a bit of work, there was at the very least an actual culmination of mechanics that could resemble the finished product.
I know this is VERY early and still needs work, but here are some 'bugs' that I encountered just so you know...
1: Able to interact with objects when not facing them, just need to be close. Some can be interacted with when they aren't there anymore, like with the Philosaur at the beginning.
2: Able to move while the backpack is open, not sure if that's intentional and doesn't actually break anything, Just something to keep in mind.
3: If you use the Pringleballs again in the same area you caught the Philosaur it freezes and seemingly needs to be restarted to fix.
4: When starting a battle, if ITEM is chosen first it goes to the FIGHT selection screen, every other button seems to work if chosen first. If PRINGLEMON is selected first it seems to fix the ITEM button to actually be able to select the item without wasting a turn first.
5: When selecting an attack that has 0 uses left, it can still be used to do damage/effects even though it says "attack missed".
All in all, keep up the good work...
