Congrats on finishing your game! The custom art wasn't really my cup of tea, but you've done a huge amount of work in a month! Well done!
The game could do with a thorough proofreading since there was quite a lot of errors. I did find it a bit hard to engage with the story as well, I wasn't really feeling anything at the end, which isn't what you want in a scene that's supposedly tense. Some of that is due to the short length (took me under 30 min), but other times I did find the characters robotic. The faces could have done with some small tweaks to things like nose and eye shape to stop everyone looking the same.
I liked the idea behind the PSY cards. I spent most of my time running from random encounters but was still able to finish the boss fairly quickly.
There were a few bugs/things to improve;
The immediate battle after buying the wooden sticks means there's no chance to equip them. Personally I think toy swords would make more sense than a shop selling a bunch of twigs, but I digress...
You don't actually get the PSY in your inventory until after the night scene, when it should be immediately in the shop. We also pick up stimulants without actually receiving any.
If you go back to the school at night, all of the npcs are still there which seems a little odd.
You can remove TP by going into the database> system and just unchecking it.
Hope this helps!
