The Alien Defense Game! #games

Instructions

Instructions: Left and Right arrow to move.. left and right (lol) Space key to shoot. After you die it is NOT game over, you keep your points and you can use them to buy upgrades! Remember to Like and Favorite! (or not I guess) Thank you to @RIMESD and @JefferyTheOriginal for complaining *AHEM* I mean "playtesting" my game! Known Issues: Shop still asks you to buy an upgrade even when you exit the shop without answering. Devlog: 6/13/2024: First view lol 6/14/2024: Removed Health Logging and Added Venus World "you win" screen, fixed a bunch of ANNOYING bugs 6/17/2024: 20 views!!! Imma start working on updates tomorrow. Mercury here we come! 6/18/2024: MERCURY UPDATE!!!!!!! (New World, new enemies, xenopedia entries, and bugfixes!) Also FIRST LIKE, FAVORITE, AND FOLLOW! TYSM! 6/20/2024: Trying to make it more clear to get upgrades. New upgrades will be added soon! Also 30 views 11/23/2024: It's been a while... More updates... fixed a few bugs. 11/26/2024: Fixed bug where Mercury boss would not display boss health properly. 11/20/2025: Okay I stopped updating this but I have started to work on this again. I added overheating to prevent people from spamming too much and fixed a bug related to the Mercury boss lava spawning. 11/21/2025: 60 views, 6 likes, 6 favorites, and 7 comments (shut up) -- Ok lots of updates today. First I got rid of overheating due to balancing issues, I'll reintroduce later. Second the mars boss is harder. Instead of blasting randomly, it shoots at the player so make so you don't get cornered. THIRD the spaceship looks better now, but the upgrades are broken so I'm going to fix them. ALSO WHEN WAS THIS ADDED TO A STUDIO? 11/22/2025: Upgrades have been fixed. New upgrades that weren't in the original that have been added: Laser synthesizer (laser size) radiator (heat loss) insulator (heat cap increase) plasma coolant (lowers the amount of heat generated from shooting a laser) and ventilation (increases the speed of losing heat). Also if you couldn't tell already I'm readding overheating so go cry about it. Also the upgrade screen now looks better! 12/7/2025: Forgot to update this log for a while. Anyways, 20+ comments is crazy (even though they're from the same people.) :/ ANYWAYS SAVE FEATURE AND LOAD FEATURE (are you happy now Rosako4444?) 12/15/2025: Volume switch added - Suggestion by Rosako4444. Quit button added - Suggestion by Rosako4444. 12/16/2025: Bugs with Quit button resolved: Quit button disappeared when it shouldn't have, and quit button didn't disappear when it should have. TBH I'm kinda lost on what to do with this game rn so imma work on my other projects 12/17/2025: People were dying for "no reason" during Butterfly Queen fight, fixed it! ALSO the save code 12/24/2025: Not sure when this happened but we got 100 views! hooray.
