hm. There is definitely a good Metroidvania skeleton here, but there are also many issues.
The character feels extremely stiff… the physics just feel really janky. The wall grab constantly caught my character while jumping, and then you have to wait a couple seconds to unstick from the wall. There are no invincibility frames after taking damage, so you can quickly drain all your health. The map says “8/8 pickups” right from the beginning, and getting new abilities doesn’t change that. The abilities themselves are just words… So it’s impossible to know when you actually got them (the health upgrade pickup didn’t actually add any health to my character). The level design and room designs are extremely basic and never pose much challenge, just a couple jumps and your done. For bugs, my character got stuck in a wall once but otherwise it was smooth sailing.
But for a game jam, I can see potential in it. If those issues were fixed, the room design refined, more enemies and interesting mechanics… it could be a solid game
