Thank you!
And I do like roguelikes! I had an idea to make the tower endless and you'd gather powerups with each level, but this was too much to do in the given time, sadly
You change color (health bar) throughout the game as you're hit by enemies, taking damage if you stand on approximately the same color as yours - but I have noticed that some colors seem to trigger damage-taking faster than others. Not sure why - the game just calculates the hue difference and checks if the difference is below a threshold.
(Actually - I think what might've happened is that the difference is calculated wrongly: 'red' has a hue value of 0, whilst 'very-very-very close to red but a biiiit more purple' has a hue value of 1, so the game would think the difference in hue would be very big, whilst in-game the colors are similar!)
Still happy that you enjoyed it!
