Irradiant

About this game

Irradiant is a minimal 2D, score-attack action game where you're faced with destroying mischievous spirits bewitching a shrine as fast as possible. You'll need to thread the needle on precision movement, button mashing and careful use of soul charges - your resource for unleashing devastation screen-wide slashes. Do you play safely at the cost of score? Or push your skills to the limit to shave off precious seconds? Your achievements can be viewed by all, with the online leaderboard. Replay your best run or watch others to see what techniques they use.

Will you live long enough to face Kaizen and bring silence to the shrine?

• Highly responsive controls, it's up to you to master your abilities to obtain the best score you can.
  
• Time ticks away, hesitation will only hurt you.

• Light attacks are as quick as your fingers and give you air time.
  
• Heavy attacks have a cooldown but deal extra damage and fling you upwards.
  
• Collect soul charges to unleash a powerful slash attack, but beware: enemies you kill with it won't reward you with more soul charges.
  
• Use the environment to your advantage with wall jumps and dashes to speed towards enemies as they appear.

• Compete for the top of the leaderboard, where every second counts.
  
• Watch replays of leaderboard scores to discover new techniques.
  
• Custom engine with minimal hardware requirements.

Playing with a controller is highly recommended. Music by Peritune. Voice effects by Voicevox.

  Achievements & Challenges

  It's been a little while but now it's time for a surprise update in celebration of Irradiant hitting over 400 leaderboard entries. Originally this update was going to just add achievements, but that felt a bit lame - so instead I've included some new challenges and a new unlockable mode. I hope you have fun discovering the new content! Achievements Nineteen achievements have been added. Score based achievements are retroactively earned on launch based on your high score. New Mode: Trials Four new trial challenges have been added. Trial of Water disables slash attacks - no quick kills on Obonyas now! Trial of Stone disables dashing - positioning and control become more important! Trial of Air disables heavy attacks - Monotori and Ryoujin are trickier to deal with! Trial of Fire disables light attacks - race to make sure you kill Iriguchi before they clam up! New Mode: Master Mode A new unlockable mode that modifies enemies for a truly merciless experience. I'll leave it up to players to discover the changes in Master Mode. Fixes Quick restart now also works on victory and defeat screens. This will probably be the last non-bug fix update but be on the look out for my next games!

  Version 1.2.0

  This update ended up being a lot more involved than I first thought, but finally there's rebinding controls! Added the ability to browse through multiple pages in the top leaderboard. Added quick restart (defaults to "R" on keyboard and unbound on controllers) which lets you quickly restart a run without confirmation. Added controls section to settings where you can rebind keyboard and controller inputs. Instructions throughout the game are now dynamic and reflect what key/button you've bound actions to. Please note if you previously customized the controls by hand they'll be reset on first launch after the update. Leaderboard names with characters not in the custom font will display "?", rather than misaligned boxes.

  Version 1.1.2

  Apologies for the update spam and not catching the root issue for this crash sooner! Fixed seg-fault crash when spawning the boss if an obonya (lantern) had some of its kaenya (wisps) already defeated.

  Version 1.1.1

  Thanks to Eglaios for catching this! Itazurakkos (imps) now only spawn from the first opening of iriguchis (mouths). After that only koumori (bats) will spawn. Note that previous recordings will not show this change in order to not disrupt current scores.

  Version 1.1

  Quick update to cover some requests. Victory and defeat screens now tells the player if they got a new high score and their new ranking. Player's global rank is displayed alongside their score, in the top right, whilst playing. Pressing menu/escape while playing will now warn the player that they need to press menu/escape again to quit to avoid nasty surprise that pausing isn't supported. Added a "controls.kohi" file which can be edited in any text editor to rebind keyboard controls. In future will investigate spending time exposing these in settings UI. Fixed a rare crash on reaching the boss.
