Hey there! Programmer here. Thank you for playing our game!
This version is just a vertical slice, a showcase of everything the full game would have to offer. That's why it's so short.
It seems like you ran into some unfortunate issues while playing. We hope you were still able to enjoy the game at least a little bit despite the problems!
Regarding the keys, a future version will feature a randomization system so that the items don't always spawn on the same locations each time. That should add some replayability to it. As for the enemy, he can teleport to certain objects! Try not to stay near them for too long...
Either way, we're really happy that you decided to cover our game and we appreciate all of your feedback! Thank you again for taking the time to play it!
