Good game.

God, I want a full version so badly :(

Good Game,i like this

Oof... closet zombie made me jump.

Great job my dude

great dude my job

Job great dude my

Any plans on a downloadable version?

Seriously good game, haven't beat it yet but damn. If this was on the gameboy, it would have been one of the best on the system and a worthy Res Evil game.

Congrats for creating this!! Total RE vibe.  Taking into account you created this in a gamejam, the mansion/maze level desing is excellent and longer than expected. I died 3 or 4 times before finishing the game and during these tries I gradually learned how to use the knife and also memorized every corridor of the mansion which is the actual point in a survival horror game.  Aesthetics are simple, but also have a nice mysterious feel. As zombies come closer the tension builds up which is always good. That final boss desing is genuinely disturbing,  not feeling save when that thing is close to me. Also loved the backtracking. I only have positive words for you and definitely would like to see more game content. Take my money!

Hey thank you for your comment and another thank you for the donation, glad you enjoyed it this much!

I'm obviously very late here, but man this game was wicked as hell! I started a series on Youtube and this happened to be the first one, and what a way to start it off. 

Really fantastic stuff. Captured both that classic Resi vibe and the GameBoy feel. Very neat and challenging. Good job.


thank you for your comment, I really appreciate it!

Great game! It really brings back that old Resident Evil-esque survival horror genre, I really hope to see more to come!

Nice game.

Still. I have a suggestion about inventory - it would be nice to have an option to drop items or to get rid of them. Yes, I can use chests to rearrange my inventory - but this is kinda lame and can involve a lot of backtracking.


I'm gonna need a Steam release ASAP xD

Damn, I really enjoyed this! I want to give some suggestions if you're looking to work on this past the gamejam. I'm sure these are all stuff you already had in mind but:

  • Spatial sfx for zombies so I know if one spawned behind me. Got hit from behind by 1 zombie. Luckily you added a vff and sfx for getting hit.
  • Run button
  • I'm told I unlocked the door before going through one that required the key I got for it. This would also go with showing un/locked doors in map.
  • More visuals in hallways and rooms like unique looking portraits or furniture. This would help with remembering which door in which room needed unlocking once the key is found. The visuals would help me remember a room better and the door that was locked in that room.
  • Extra effect to let player know whether the zombie is close enough to attack or not. Maybe more sprites in between the 3-5 far to close zombie sprites. Wasn't to hard to figure out how long it takes a zombie to attack once they're super close though.
I really like the fact that the mouse is used for weapons/interaction as it made me feel like my hand was the avatars' hand. Sometimes I would try to move the mouse to aim like a shooter. I wonder if there's a way to tackle this issue but I was doing it less and less as I kept playing, so it wasn't so bad. The music was pretty eerie and the more it kept replaying, the more the soft and the intense parts of the music would creep me out. I like the references to RE like the "Itchy tasty" note and the sfx are reminiscent of the old RE as well. Reached the last note! Will be following you for more cool work like this!

*Rawr!* Hello everyone! I gave the game a Let's Play and had great fun, reminded me of the days of Gameboy, but also games like Resident Evil: Survivor, which I infact played and beat as a kid long ago xD Anyways, video below to showcase the gameplay - hope you expand on this game, and hope people enjoy my video!

Great game, controls setup are a little to weird.
