We have updated our Itch page:
Bug Note: We have discovered, thanks to Dan Collins, a bug in our game with the thwomp spike speed. However, thanks to a kind soul in the Metroidvania Month Jam Discord server, we have discovered there is a simple fix: If you encounter ultra speed thwomp spikes, you simply need to quit the game (you should be able to Resume at your last checkpoint!), turn Vsync in your GPU settings to ON, and run the game again. This seems to clear the problem up.
We will be issuing a patch build after the Metroidvania Month 22 jam is done; it appears we cannot patch during voting time. Thanks again to everyone and hope you enjoy our game!
