Cool game. Impressive how many systems you managed to implement - topdown fighting, inventory - everything feels polished and UX is great.
I did not manage to get through the last door - I collected up to 54 , but the door needed 58. Not sure where I missed an upgrade.
Some small bugs:
- in some areas clicking does not start charging attack, it just does nothing
- after I played for a while, mostly when looking for missed upgrade, FPS started dropping and after a few minutes I was getting <10 FPS. Maybe some nodes are not being freed and are piling up?
