(Sorry for two comments)
Pro-Tip for level 19: Start off red/black. Go up. Click to turn white/blue, then move back a little. After the wave of white/blue bullets have passed, turn red/black and move forward. Repeat this process until you reach the goal, it worked for me :)
Currently stuck at level 16. It's a very fun but frustrating game. It's so satisfying to beat a level (higher than level 3 that is). It's also innovative. When you lose, it feels like it's YOUR fault, and not just the game being cheap.
5/5. Great game, great music, nice retro feel, great-looking sprites.
However, the only things I dislike about this game are the fireballs. They can appear out of nowhere, and no matter how skilled you are, you can get hit by them just by pure misfortune. Either make them appear less random or flat out remove them.
Good game. I like the new things added to this game vs. other idle games. It has a lot of similarities with other idle games, but it has enough original ideas to make it different. Honestly, I'd rather play this over cookie clicker or adventure capitalist. There is an annoying graphical glitch with the scrolling background, though. I can see a green line as the background image loops. Other than that, great game. (4/5)
Thank you! Glad you're enjoying Crusaders and the update frequency. Which areas are the seams on? We do try not to have any, but some of the early areas might have escaped notice.
I love how in hard mode, you go from OP to the worst player in the game XD well since I'm stuck on hard mode, have 3 kongregate badges, and have 21/24 awards (missing "Humans win", "don't release the kracken", and "are you kidding me"), I guess I'll stop here. I rate 4/5, because it does get a little repetitive after "normal" mode.
beat the game one-hundred percent. I loved every bit of it! Very clever.
Wait, crep! I forgot to upgrade my keyboard....okay, I beat the game 100%. Wait, now I have to buy the post button! *sighs*
for those wondering the controls:
Shift - makes character flip through the ground, changing gravity as well.
Arrow keys - (obviously) make you move around. (up doesn't jump)
Space bar - for some reason, instead of the UP arrow key (the one I constantly keep hitting by mistake), space bar makes your character jump.
Up arrow - Enter doors because why not.
Ctrl - once you get to room 7, you can press control to swap between characters.
