you can see my live reaction here
things I liked:
- the little details you have everywhere is great. The rooms fading out when you exit them, seeing part of rooms and then the entire thing when you enter, etc.
- music works great with the gameplay
- having the framework in for different endings is great. Got two different ones and it didn't seem like much changed but still showing good, neutral, etc. Based on what the player did undertale style is a nice addition
- the monster designs
Things if you continue:
- having another step in the bag when you select it to choose which item who want to use. Normally if you select bag people think its going to open the bag rather than use the thing in the bag. Not major since you also only have 1 item to use but can make people accidentally use the laser gun
- at times the dialogue got to be a lot to read at once (mostly around when they were talking about the perpendicular dimension). Simplifying that a bit makes it a bit more fun to go through
- not being able to go a bit under the walls in the house felt a bit off (since due to perspective the bottom of the wall wouldn't be there. Could be fixed by having a separate tilemap for colliders and then putting less high ones there or assigning less high colliders to those specific tiles
